Abstract: A process cartridge, which includes a developing cartridge and a photosensitive cartridge for use with an image forming apparatus including a driving force output part and a feeding part, is provided. The developing cartridge includes a developer carrier, a first electrode provided at one side thereof, and a driving force receiving part provided at another side thereof and aligned with the first electrode such that the driving force receiving part overlaps the first electrode in a side view. The photosensitive cartridge, to which the developing cartridge is removably mounted, includes a photosensitive member, and a second electrode that contacts the first electrode when the developing cartridge is mounted in the photosensitive cartridge and that contacts the feeding part when the photosensitive cartridge is mounted in the image forming apparatus. The first electrode is pressed toward the driving force receiving part by contact with the second electrode.

Abstract: A developing cartridge includes an input gear which receives an external driving force; a developing roller which carries developer; a supply roller that is in contact with the developing roller and supplies the developer to the developing roller; a supply roller gear that is meshed with the input gear to drive the supply roller using a driving force transmitted from the input gear; and a developing roller gear that drives the developing roller with a driving force transmitted from the supply roller gear. The cartridge further includes a housing with a partition wall that partitions the housing into a first chamber that accommodates the developer and a second chamber that houses the developing roller and the supply roller, and an input gear shaft that supports the input gear. The input gear shaft and the partition wall overlap each other as viewed from a side of the developing cartridge.

Abstract: A developing cartridge includes a first frame including a first wall at one end thereof, a second frame including a pair of second walls facing with each other and a third wall that connects the pair of second walls, an opening that is formed by the first wall, the pair of second walls and the third wall, and a support that is interposed between the third wall and the first wall so as to support the first wall by the third wall.

Abstract: Aspects described herein relate to a cap for a toner cartridge. In one example, the cap may be configured to close a toner supply opening of the toner cartridge. According to one or more aspects, the cap may include a sealing or covering portion configured to cover the toner supply opening and a shaft portion for rotatably supporting a to-be-detected rotary member. The to-be-detected rotary member 56 is rotatably supported around and fitted onto the shaft portion. Therefore, even if a toner supply opening of a cartridge is provided in a sidewall of the housing on a side where the to-be-detected rotary member is provided, e.g., a left sidewall, the toner supply opening and the to-be-detected rotary member can be provided in such a manner as to overlap each other.

Abstract: A photosensitive drum cartridge and an image forming apparatus including the photosensitive drum cartridge are provided. The photosensitive drum cartridge includes: a photosensitive drum; a primary cleaning roller which is configured to contact a surface of the photosensitive drum to remove an attached matter on the surface of the photosensitive drum; a first gear which is configured to rotate together with the photosensitive drum; a second gear which is configured to rotate together with the primary cleaning roller; and a third gear which is configured to mesh with the first gear and the second gear, and which has a rotation axis, a position of which is fixed such that a distance from a rotation axis of the first gear is constant.

Abstract: An image forming apparatus includes a first developing cartridge and a first photosensitive cartridge. The first developing cartridge is removably mounted in the first photosensitive cartridge and includes a toner hopper, a supply roller and a developing roller. The first photosensitive cartridge includes a photosensitive drum, a charger provided at a position adjacent to the photosensitive drum, a first wall provided adjacent to the supply roller, the toner hopper, and the developing roller when the first developing cartridge is mounted in the photosensitive cartridge, the first wall including a first opening, and a second wall which faces the first wall and is provided adjacent to the charger, the second wall including a second opening on an opposite side of the charger from the photosensitive drum. A portion of a wall of the first developing cartridge projects through the first opening in the first wall of the first photosensitive cartridge.

Abstract: A developing cartridge is provided. The developing cartridge includes an input gear which receives an external driving force; a developing roller which carries developer; a supply roller that is in contact with the developing roller and supplies the developer to the developing roller; a supply roller gear that is meshed with the input gear to drive the supply roller using a driving force transmitted from the input gear; and a developing roller gear that drives the developing roller with a driving force transmitted from the supply roller gear.

Abstract: A developer cartridge includes a cartridge cabinet configured to accommodate developer. The cartridge cabinet includes a cartridge-side opening that allows communication between an inside of the cartridge cabinet and an outside of the cartridge cabinet, and a slope provided at a lower edge of the cartridge-side opening, the slope inclining in a direction crossing a horizontal direction when the cartridge-side opening is oriented in a horizontal direction.

Abstract: A developer cartridge including a frame, a developer carrying member, and an input gear member is provided. The frame includes a first side wall and a second side wall, and the first side wall and the second side wall extend in a length direction. The developer carrying member extends from the first side wall to the second side wall in a width direction perpendicular to the length direction. The developer carrying member includes a developer carrying member shaft rotatably supported by the first side wall and the second side wall, and the developer carrying member is rotatable about a first axis. The input gear member, for supplying a driving force for rotating the developer carrying member, is rotatably supported by the first side wall so as to be rotatable about a second axis. A first distance between the first axis and the second axis in the length direction is about 14.0 mm.
