摘要： An imaging device provided with a latent image carrying body rotatably disposed to carry a latent image, a developing unit that develops the latent image carried on the carrying body by using a developer containing toner at least, and a duct disposed downstream of the developing unit and having a wall with an upstream suction port and a downstream suction port formed. An air flow path is formed by a surface of the latent image carrying body and a surface of the duct wall, between the upstream suction port and the downstream suction port. A gap of the air flow path is wider at the downstream side than at the upstream side with respect to the rotational direction of the latent image carrying body.

摘要： A developer supply system includes a container, a memory, and a positioning mechanism. The container has a deformable bag formed of flexible material to accommodate developer therein. The memory is attached to a given planar surface of the deformable bag to store information for communication to the image forming apparatus. The positioning mechanism holds the container therein while maintaining the given planar surface in position relative to the image forming apparatus when the deformable bag collapses as it discharges developer. An image forming apparatus employing such a developer supply system is also disclosed.

摘要： A toner supply device includes a toner container, a transport-path forming member, an opening, a shutter member, and a first seal member. The opening is provided at a side wall of the transport-path forming member. The shutter member is movable between a closed position to close the transport path by being inserted in the opening and an open position. The first seal member fills a gap between an inner wall of the opening and the shutter member in a toner transport direction in which the toner is transported through the transport path. When the shutter member is inserted in the opening, the shutter member is elastically deformable in a deformation direction perpendicular to both the toner transport direction and a moving direction of the shutter member, and when the shutter member is not inserted in the opening, the shutter member is wider than the opening in the deformation direction.

摘要： To provide a relatively small developing device, process cartridge and image forming apparatus that prevent developer, accommodated in a second developer conveying portion for recovering the developer after a developing step, from being pumped up to a developer carrier, and that do not apply a large stress to the developer. A plurality of developer carriers are arranged side-by-side in a direction of gravitational force so as to face an image carrier. The developing device comprises a first developer conveying portion that supplies the developer to a first developer carrier, a second developer conveying portion that recovers the developer separated from the second developer carrier, and a third developer conveying portion that conveys the developer obliquely upward and conveys, to an upstream side in a conveyance direction of the first developer conveying portion, the developer reaching the downstream side in the conveyance direction of the first developer conveying portion and the developer reaching a downstream side in a conveyance direction of the second developer conveying portion.
