Abstract:
A toner recovery device includes a toner recovery container that recovers toner; and a toner conveying shaft member that is provided inside the toner recovery container and conveys toner in a axial direction of the toner conveying shaft member by the rotation around a rotational axis of the toner conveying shaft member and that has a spiral groove formed around the rotational axis and an outer peripheral surface whose distance from the rotational axis is variable.
Abstract:
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 storage container includes a main body portion and a rotary cylindrical body. The main body portion has a cylindrical inner peripheral surface and a pair of main body side end surfaces. The rotary cylindrical body has a side surface having a cylindrical shape, a pair of rotary body end surfaces and a storage space configured to store developer. A slit extending is formed on the side surface of the rotary cylindrical body to allow communication between the internal space and the storage space. The rotary cylindrical body is so arranged in the internal space that a predetermined clearance is defined between the side surface and the inner peripheral surface of the main body portion. A developer discharge port is opened on the main body portion.
Abstract:
A developer container includes a container body, a lid, a developer discharge port, a shaft, and a movable wall. The container body includes an inner surface defining a cylindrical internal space and a wall disposed at one end of the container body. The container body is formed with the developer discharge port. The lid is attached to the other end of the container body. The shaft includes a first engaging portion. The movable wall includes a conveying surface and a carrier bearing. The conveying surface defines a storage space configured to contain the developer. The carrier bearing includes a second engaging portion. The movable wall is movable along the shaft in the first direction while conveying the developer by engagement of the first engaging portion and the second engaging portion. The first engaging portion includes a small pitch part having a relatively small thread pitch.

Abstract:
A developer container includes a container body, a movable wall, and a detection sensor. The container body includes an inner surface defining a cylindrical internal space. The internal space is in the form of a cylinder extending in a first direction. The container body is formed with a developer discharge port communicating with the internal space. The movable wall includes an outer surface and a conveying surface. The outer surface is disposed in close contact with the inner surface of the container body. The conveying surface defines a storage space configured to contain the developer in cooperation with the inner surface of the container body. The movable wall moves in the first direction from one end side to the other end side of the internal space. The detection sensor is provided on the container body near the developer discharge port and detects the developer in the storage space.
