Abstract:
Provided are a developer storage container in which a large change of a developer distributed state due to a backward movement of a moving wall is restrained and an image forming apparatus provided with the developer storage container. A toner container includes a container body, a moving wall and a shaft. The moving wall includes a first wall portion and a second wall portion. When the shaft is rotated in a first rotating direction, the second wall portion presses the first wall portion, whereby the second wall portion moves in a first direction integrally with the first wall portion. When the shaft is rotated in a second rotating direction, the second wall portion relatively moves to an upstream side in the first direction with respect to the first wall portion.
Abstract:
An image forming apparatus includes a developer container having a movable wall therein, a determination unit, a movable wall driving unit, and a movable wall driving controller. The determination unit outputs first determination information when a number of outputs of a signal indicating that a detection sensor has detected a developer is less than a threshold value, and outputs second determination information when the number of outputs thereof is equal to or greater than the threshold value. The movable wall driving unit includes a first driving motor for moving the movable wall and a first driving circuit for controlling driving thereof. The movable wall driving controller includes a signal controller. The signal controller transmits a drive permission signal for the first driving motor when the first determination information is output, and transmits a drive non-permission signal for the first driving motor when the second determination information is output.

The connector portion is located on the apparatus main body and includes a first input/output terminal. The developer housing container is removably mounted to the developing device. The developer housing container includes container body that houses a developer to be replenished to the developing device and a storage unit mounted to an outer surface of the container body. The storage unit includes a second input/output terminal for electrical connection to the first input/output terminal. In a state where the developer housing container is mounted to the developing device, the developer housing container has a posture changeable between: a first posture where the second input/output terminal is separated from the first input/output terminal, and a second posture where the second input/output terminal contacts the first input/output terminal to be electrically connected.
Abstract:
A developer storage container (30) includes a container body (37), a developer discharge port (377), a movable wall (32) and a stirring member (35). The movable wall moves in a first direction in an internal space from an initial position on one end side in the first direction to a final position on the other end side while conveying developer in a container space toward the developer discharge port. At the final position of the movable wall, an upstream end portion of an outer circumferential portion of the movable wall in the first direction is disposed upstream, in the first direction, of an upstream end portion of the developer discharge port in the first direction and a conveying surface of the movable wall is disposed at a distance from the stirring member.
Abstract:
An image forming apparatus includes an apparatus body, an image carrier, a developing device, and a developer container. The developing device includes a developer supply port and a mounting section. The developing device is mounted onto a developing position facing the image carrier through a specific insertion path in the apparatus body. The developer container includes a developer discharge port. The developer container is mounted onto the mounting section of the developing device through the insertion path. The developing device is dismounted from the apparatus body through the insertion path after being rotated from the developing position to a standby position in a first direction around a first axis extending in parallel with a rotary axis of the image carrier. The developer container is dismounted from the apparatus body after being rotated in a second direction opposite to the first direction around a second axis in the mounting section.
Abstract:
A developer supplier includes a developer container and a main unit. The main unit includes a mounting section. The developer container includes a container body, a developer discharge port and a container shutter. The main unit includes a housing, a developer supply port, a main unit shutter, and a biasing member. The biasing member biases the main unit shutter to the developer supply port. The developer container is mounted into the mounting section in a first orientation, and is subsequently rotated in a first rotational direction so that the developer container changes to a second orientation. The main unit shutter moves in the first rotational direction against a biasing force of the biasing member so that the developer supply port is exposed. The container body rotates in a second rotational direction owing to the biasing force so that the developer discharge port is covered by the container shutter.

The container shutter covers or exposes the developer discharge port. The container shutter includes a container shutter body and a container sheet member. The main unit includes a housing and a main unit seal. The housing has a developer supply port. The developer container is mounted into a mounting section in a first orientation, and subsequently the container body is rotated in a first rotational direction so that the developer container changes to a second orientation and the developer discharge port communicates with the developer supply port. The container sheet member has a downstream end and configured to come into contact with the main unit seal when the developer container is mounted into the mounting section in the first orientation.
Abstract:
A developer supplier includes a developer container and a main unit. The main unit includes a mounting section for allowing the developer container to be mounted therein. The developer container includes a container body, a container shutter and a developer discharge port. The container shutter is supported on the container body and covers or exposes the developer discharge port. The main unit includes a housing and a guide mechanism. The housing is formed with a developer supply port. The developer container is mounted into a first position of the mounting section while being guided in a first direction by the guide mechanism, and subsequently the container body is rotated from the first position to a second position in a first rotational direction to thereby move and expose the developer discharge port away from the container shutter so that the developer discharge port communicates with the developer supply port.

A developer container (30) includes a container body (31) and a movable wall (34). The container body (31) includes an inner surface (31K) defining a cylindrical internal space (31H) extending in a longitudinal direction, and a developer discharge port (319). The developer discharge port (319) is formed in a lower part of the inner surface (31K). The movable wall (34) includes an outer surface (34K) disposed slidably in contact with the inner surface (31K) of the container body (31), and a conveying surface (340S). The conveying surface (340S) defines a storage space (31S) for containing developer in cooperation with the inner surface (31K). The movable wall (34) moves in the longitudinal direction from one end side toward the other end side while conveying the developer in the storage space (31S) to the developer discharge port (319).
Abstract:
A developer container includes a container body, a movable wall, and a stirring member. The container body is formed with a developer discharge port opening in a circumferential portion of the container body and communicating with an internal space for allowing discharge of developer therethrough. The movable wall includes an outer surface slidably in close contact with an inner surface of the container body, and a conveying surface defining a storage space for the developer, the movable wall being movable in the first direction in the internal space while conveying the developer in the storage space to the developer discharge port. The stirring member faces the developer discharge port in a direction intersecting the first direction and is rotatable to stir the developer in the storage space. The movement of the movable wall and the rotation of the stirring member are controlled independently of each other.
