  • Patent number: 11940755
    Abstract: Disclosed is a process cartridge detachably mounted to an image forming device having a tray and force applying components. The process cartridge has a process cartridge frame, a photosensitive unit, a developing unit rotatable relative to the photosensitive unit. The process cartridge frame has a driving side and a conductive side disposed oppositely along a length direction. The driving side has a first driving force receiving portion for rotating a photosensitive drum and a second driving force receiving portion for rotating a developing roller. The developing unit has a force receiving portion for receiving force of force applying components to rotate the developing unit relative to the photosensitive unit. When the process cartridge is pushed into to the image forming device, the force receiving portion move at least in a left-and-right direction and/or an up-and-down direction relative to the frame of the process cartridge.

  • Patent number: 11016439
    Abstract: There is provided a process cartridge that includes a driving assembly engageable with a driving shaft having a recess in an image forming apparatus. The driving assembly includes a coupling member, configured to receive a driving force from the driving shaft and provided with a power receiving portion engageable with the recess of the driving shaft; and a body portion capable of rotating after receiving the driving force transmitted by the power receiving portion. When the driving assembly is mounted in the image forming apparatus, the power receiving portion can urge the axis of the driving shaft to be inclined with respect to the axis of the driving assembly. The coupling member urges the driving shaft to be inclined to implement engagement and disengagement, thus solving the technical problem in the prior art that the driving assembly has complicated molding process, high production costs and unstable transmission of the driving force.
