Abstract:
The present application discloses a developing device including a housing having a connection surface to which the container connects. The connection surface is provided with a feed port for feeding the developer. The developing device includes a shutter mechanism configured to selectively open and close the feed port. The shutter mechanism includes a shutter piece, which moves between a closing position for closing the feed port and an opening position for opening the feed port, and a squeezing mechanism, which protrudes from the shutter piece situated in the closing position to squeeze the developer into the housing through the feed port.
Abstract:
An image forming apparatus includes a groove, an exposure device and an adjustment member. In the groove, a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. The adjustment member is configured to shift the rotation shaft vertically in the groove to adjust a skew of the laser light.
Abstract:
A developing device includes a housing, a developing roller, a developer conveying section, and a conveying screw. The developing roller includes a stationary magnet, and a sleeve rotatable around the stationary magnet. The developing roller faces a photoconductive drum. The developer conveying section is disposed below the developing roller for circularly conveying developer therein. The conveying screw conveys developer to supply developer to the developing roller. The stationary magnet includes a separation pole for producing a magnetic field that causes separation of developer from the sleeve. The housing includes a standing wall disposed downstream of the developing position in a rotational direction of the sleeve and facing the developing roller. The standing wall is formed with at least one opening that faces the separation pole in a horizontal direction. The developing device further includes at least one filter section covering the at least one opening.

Abstract:
A developing device of the present disclosure includes a developing roller, a toner supply roller, a regulation blade, a casing, a toner receiving support member, a toner receiving member, a vibration generation unit, and a vibration inhibition member. The toner receiving support member is disposed in the casing so as to be opposed to the developing roller or the toner supply roller in an area between the regulation blade and an image carrier. The toner receiving member has a toner receiving surface that receives toner dropping from the developing roller, and is supported so as to be swingable about an end edge thereof on a toner supply roller side as a fulcrum. In a state where the toner receiving member is not vibrating, the vibration inhibition member is in contact with each of both end portions of the toner receiving surface in a longitudinal direction thereof.
Abstract:
An image forming apparatus includes an image forming apparatus body, a first driving mechanism, a first drive unit, an image carrier, a developing device, and a biasing member. The first drive unit includes an input unit to which a rotary drive power is transmitted from the first driving mechanism. The developing device is removably attachable to the image forming apparatus body. The biasing member biases the developing device toward the image carrier side. The developing device includes a developing roller supplying toner onto the image carrier, and a developing unit housing and supporting the developing roller. The first drive unit is located at one end portion in an axial direction of the developing roller. The developing unit swings to come close to the image carrier by the biasing member biasing the developing unit. The developing unit is swingable with respect to the first drive unit.

Abstract:
A development device includes a developer introduction port, a developer conveyance portion, a first conveyance ability suppressing portion, and a connecting conveyance portion. The conveyance ability suppressing portion is disposed on a downstream side of the developer introduction port in a first direction in which the developer is conveyed in order to partially suppress a developer conveyance ability of the developer conveyance portion such that a developer accumulation portion is formed in a position opposing the developer introduction port. A first direction downstream side of the first conveyance ability suppressing portion opposes a first connecting passage in a third direction that intersects the first direction. The connecting conveyance portion is joined to the first direction downstream side of the conveyance ability suppressing portion and opposes the first connecting passage in the third direction in order to pass the developer from a first conveyance passage to a second conveyance passage.
Abstract:
The present application discloses a developing mechanism including a developing device for developing electrostatic latent images and a container containing developer. The developing device includes a carrier carrying and supplying the developer to the electrostatic latent images; a first housing having a feed port through which the developer is fed; a first conveyance member conveying the developer along a first direction away from the feed port; and a first shutter mechanism selectively opening and closing the feed port. The container includes a second housing having a supply port from which the developer is supplied through the feed port to the developing device; a second shutter mechanism selectively opening and closing the supply port; and a second conveyance member conveying the developer along a second direction across the first direction for developer discharge through the supply port. The feed port is opened earlier than the supply port is opened.
