Patent ID: 11531301

Abstract:
A cartridge includes a photosensitive drum and a coupling member for transmitting a driving force to the photosensitive drum. A movable member is provided movable relative to a frame and a rotatable portion is supported by the movable member and rotatable relative to the movable member. A regulating member is movable between a regulating position for regulating movement of the movable member by contacting the rotatable portion and a non-regulating position where the regulating member does not regulate the movable member. A position of an end portion of the movable member in an axial direction of the photosensitive drum changes relative to the frame by movement of the movable member between a first position and a second position, and the end portion of the movable member is closer to the coupling member in the axial direction of the photosensitive drum when the movable member is in the second position than when the movable member is in the first position. When the regulating member is in the regulating position, the movable member is constrained from moving from the first position to the second position, and, when the regulating member is in the non-regulating position, the movable member is permitted to move from the first position to the second position.
