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 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 cartridge includes a casing and a photosensitive drum rotatably supported in the casing. A rotatable driven coupling member is provided on an axial end of the photosensitive drum, with the driven coupling member including a driving force receiving portion for receiving a driving force to rotate the photosensitive drum. The driven coupling member is translatable with respect to the casing in a predetermined direction, which is substantially parallel to a rotational axis of the photosensitive drum, by a force received by a driven side abutment portion of the driven coupling member. A distance between the rotational axis of the driven coupling member and the driven side abutment portion is not more than a distance between the rotational axis of the driven coupling member and the driving force receiving portion.

摘要： An image forming apparatus includes a main body, a moving member movable while supporting an image forming portion having an image bearing member, between a position inside the main body and a position outside the main body so that at least a part of the image forming portion is removably mountable on the moving member as a cartridge, and an exposure device configured to expose the image bearing member with light through an exposure opening provided in the moving member. In addition, a shielding member is provided in the moving member to shield the exposure opening, and a holding mechanism holds the shielding member in a shielding position for shielding the exposure opening while the moving member is moved and holds the shielding member in a non-shielding position for opening the exposure opening when the moving member is in the inside position.
