  • Publication number: 20250147461
    Abstract: 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.

  • Publication number: 20250102996
    Abstract: There are demands for stable connections of contact points between a process cartridge, including a development device, and an image forming device. A development contact point, a first contact point, and a second contact point are disposed in this order on the inside in a perpendicular direction with respect to an insertion direction in which a development device is inserted into an image forming apparatus.

  • Patent number: 10845723
    Abstract: An image forming unit including a photosensitive member including a gear portion on a one end side of the photosensitive member in a rotational axis direction, a roller that comes in contact with the photosensitive member, a bearing member that rotatably supports the roller, and an elastic member that urges the bearing member. In the image forming unit, directions of moments about a rotational axis of the roller acting on the bearing member disposed on the one end side of the photosensitive member in the rotational axis direction are the same in a case in which the roller is rotated and in a case in which the roller is stopped.
