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： 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： A developing device which can stably supply a developer to a latent image carrier by preventing the scattered developer from being discharged and thereby preventing the developer from being discharged despite that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw serving as a developer conveying member moves toward a developer discharge port. Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.
