Patent number: 12429811Abstract: 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.Type: GrantFiled: June 9, 2020Date of Patent: September 30, 2025Assignee: Canon Kabushiki KaishaInventors: Naoki Matsumaru, Ryuta Murakami, Tadashi Horikawa, Akihiro Fujiwara, Akinobu Hirayama, Daisuke Makiguchi, Hiroaki Nosho, Takuro Kanno, Goshi Ozaki, Tachio Kawai, Daisuke Abe
