Abstract: A cartridge includes a photosensitive drum and a developing roller, with the developing roller being configured to develop a latent image formed on the photosensitive drum with toner. The cartridge also includes a first electrical contact electrically connected to the charging roller and the second electrical contact electrically connected to the developing roller. As viewed along the axis of the photosensitive drum, the first electrical contact and the second electrical contact are positioned on opposite sides with respect to a line that passes through an axis of the photosensitive drum and an axis of the developing roller.

Abstract: Provided is a process cartridge where a developing unit includes a coupling member that receives driving force, a driving transmission member that transmits the driving force from the coupling member to a driving roller, and a support member that rotatably supports the coupling member and is movable with respect to a developing frame in a direction intersecting with a rotational axis of the developing roller. The developing frame and the driving transmission member are configured to be movable with respect to a drum frame of a drum unit in the direction intersecting the rotational axis. In this process cartridge, an urging member that engages with both the support member and the drum frame is included such that an urging force is applied in a direction in which a positioned portion of the support member and a positioning portion of the drum frame contact each other.

Abstract: A cartridge includes a photosensitive drum supported by a frame, a coupling positioned at an end of the photosensitive drum, with the coupling being configured to receive a driving force for rotating the photosensitive drum. A lever is movably supported by a part of the frame at a position that is adjacent to the end of the photosensitive drum, with the lever being movable between a first position and a second position. As viewed along the axis of the photosensitive drum, an end of the lever is a first distance from the axis of the photosensitive drum when the lever is in the first position, and the end of the lever is a second distance from the axis of the photosensitive drum when the lever is in the second position, with the second distance being greater than the first distance.

Abstract: A cartridge includes a photosensitive drum, the movable member movable relative to the photosensitive drum to control an inclination angle of a drive transmission member. The movable member is movable between a first position for reducing an inclination angle of the drive transmission member relative to the photosensitive drum and a second position retracted from the first position. By this, driving connection can be smoothly carried out.

Abstract: A cartridge mountable to and dismountable from a main assembly of an image forming apparatus includes a memory, a guide configured to guide a portion-to-be-guided provided in the main assembly and to guide a main assembly contact provided in the main assembly to a memory contact of the memory when the cartridge is mounted in the main assembly, and a grip portion. The guide is provided at a bottom of the cartridge when the cartridge is hung by gripping the grip portion and constitutes a part of a supporting portion configured to support the cartridge when the cartridge is placed on a horizontal placement surface. The guide has a chamfered surface formed by being chamfered. When the cartridge is supported at the supporting portion, the chamfered surface opposes the horizontal placement surface, and a surface of the memory contact is inclined with respect to the horizontal placement surface.

Abstract: A process cartridge includes a first unit including an image bearing member to bear a developing agent image, a second unit including a development frame member in which a developing agent bearing member to bear a developing agent to be supplied to the image bearing member is supported, and a coupling portion that can couple the first and second units such that the second unit is swingable with the coupling portion as a rotation center. The development frame member includes a replenishing opening for the developing agent, and an elastically-deformable sealing member that seals the supply portion and the replenishing opening. As viewed along a compression direction of the sealing member, in a section orthogonal to a longitudinal direction of the process cartridge, the rotation center is disposed at a position overlapping with the sealing member.
