摘要： An image forming apparatus includes an apparatus main body and a movable member configured to move with respect to the main body while supporting an image bearing member and a developer bearing member. The movable member is movable to a position located inside the main body, where the two bearing members is in an image formable state, and a position located outside the main body, where a cartridge including the developer bearing member is detachable from the movable member. The apparatus further includes an exposure device configured to expose the image bearing member via a light transmission member, and a cleaning member configured to clean a surface of the light transmission member opposed to the movable member. The cleaning member is provided on the movable member and is movable to a contact position for contacting the light transmission member and a noncontact position when the movable member moves.

摘要： A developing unit, which is attachable to and detachable from a photosensitive member unit, includes: a developing roller; a housing in which a holding space that holds toner is formed; and a pressing receiving portion that receives pressing force from a pressing member. The housing includes a first bottom portion that projects toward an outer side of the holding space, and a second bottom portion that projects toward the outer side of the holding space, in a state in use. When viewed in a direction of a rotation axis of the developing roller, at least part of the pressing receiving portion is located in a space surrounded by the first bottom portion, the second bottom portion, and a tangent line tangent to both an outer wall of the first bottom portion and an outer wall of the second bottom portion.

摘要： A cartridge includes a projection portion provided in a first region of an upper surface of a frame in a vertical direction. The projection portion projects more upward than second regions between which the first region is interposed. An inside of the projection portion is a space that is part of a developer accommodating portion. The projection portion is configured to pass through a space under an abutting portion while being elastically deformed by the abutted portion being pressed by the abutting portion after the cartridge is transitioned from the first posture to the second posture in accordance with movement of the cartridge in the attaching direction.

摘要： A cartridge includes a drum unit and a development unit. The drum unit includes a photosensitive drum, a frame, a transfer roller, and a cleaning member. The development unit includes a development roller, and a memory. The cleaning member is configured to come into contact with the photosensitive drum at a region between a development nip portion and a transfer nip portion in a circumferential direction of the photosensitive drum and at an end portion of the photosensitive drum in a direction of the rotational axis. The frame has an exposing hole through which the memory is exposed from the frame, and a recessed portion that is adjacent to the exposing hole in the direction of the rotational axis, and stores foreign matters removed from the photosensitive drum by the cleaning member.

摘要： A process cartridge includes a photosensitive member and a developing unit. The developing unit includes a frame to store toner, a developing roller to carry the toner, a side seal to contact an end portion of the developing roller and prevent the toner from leaking out, and a sealing sheet to contact a center portion of the developing roller and prevent the toner from leaking out. A toner receiving portion of the frame includes an opening facing the developing roller and is disposed on an upstream side of the side seal and a downstream side of a contact portion where the developing roller contacts the photosensitive member, and moreover is disposed at a position overlapping with the side seal. The developing unit includes a blocking member to block at least a part of the opening, and the blocking member is disposed between the opening and the developing roller.

摘要： With a structure in which a coupling member includes a sphere providing a center of inclination (pivoting), a rotational force transmitted member has an opening have a diameter smaller than that of the sphere, and the coupling member is prevented from disengaging from rotational force transmitted member by contact of inner edge of the opening to the sphere, the inner edge of the opening may limit an inclinable (pivotable) angle range of the coupling member. In a state that a pin that is a shaft portion is inserted in a hole that is a through-hole provided in a coupling member, opposite end portions of the pin are supported by a driving side flange, which is a rotational force transmitted member. The coupling member, the driving side flange, and the pin are connected in this manner, and the pin contacts the inside of the hole without limiting the inclinable angle range.
