摘要： A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.

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.

摘要： The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the bulk of the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from reaching the level where the recovered developer re-adheres to a developing roller, and further the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from re-adhering to the developing roller.

摘要： A developing device capable of preventing deterioration of the image quality, which is caused when a developer recovered by a developing roller re-adheres thereto, and an image forming apparatus equipped with the developing device. The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the amount of developer existing on the upstream side of the agitation conveyance path in the developer conveyance direction becomes small, whereby the developer can be delivered smoothly from the recovery conveyance path to the agitation conveyance path. Therefore, the bulk of the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from reaching the level where the recovered developer re-adheres to a developing roller, and further the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from re-adhering to the developing roller.
摘要翻译：一种能够防止由显影辊回收的显影剂重新附着的显影剂的图像质量劣化的显影装置和配备有显影装置的图像形成装置。在显影剂输送方向上的搅拌输送路径的上游侧的显影剂输送量比通过将回收输送路径向搅拌输送路径输送的显影剂的量变大，显影剂输送方向上的搅拌螺杆等于或大于在显影剂输送方向上的回收螺杆的下游侧的显影剂输送量。因此，显影剂输送方向上的搅拌输送路的上游侧的显影剂的量变小，能够使显影剂从回收输送路径平稳地输送到搅拌输送路径。因此，可以防止在显影剂输送方向上在回收输送路径的下游侧存在的显影剂的体积达到恢复的显影剂重新粘附到显影辊的水平，并且进一步存在于下游侧的显影剂可以防止显影剂传送方向上的恢复传送路径再次粘附到显影辊上。

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： An insertion passage 104Y for inserting a suction nozzle 73Y fixed to an image forming apparatus is provided on a holder 102Y, and a connecting passage 114Y that connects the insertion passage 104Y and a toner storage section 106Y of the holder 102Y is provided. After the toner sent from bottle 101Y to the holder 102Y falls towards the connecting passage 104Y, the toner flows into the suction nozzle 73Y through the connecting passage 114Y and is then discharged out of the holder 102Y. An airtightness between the insertion passage 114Y and the suction nozzle 73Y inserted into the insertion passage 114 Y is superior than an airtightness between the bottle 101Y and the holder 102Y engaged with the bottle 101Y.
