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.
