Patent number: 11927910Abstract: 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.Type: GrantFiled: March 21, 2023Date of Patent: March 12, 2024Assignee: Canon Kabushiki KaishaInventors: Ryuta Murakami, Daisuke Makiguchi, Goshi Ozaki, Daisuke Abe, Tachio Kawai
