Abstract
The present disclosure provides a process cartridge detachably mountable to an electrophotographic image forming device. The process cartridge includes a housing, a coupling component provided at one end of the housing for receiving rotational driving force from a driving head inside the electrophotographic image forming device, and a limiting protrusion provided at the other end of the housing. The limiting protrusion abuts a lateral wall in the electrophotographic image forming device when the process cartridge is installed into the electrophotographic image forming device, and a guiding surface is provided at the limiting protrusion. Further, the guiding surface abuts the lateral wall in the electrophotographic image forming device, and a rotational axis of the coupling component inclines with respect to a rotational axis of the driving head when the process cartridge is detached from the electrophotographic image forming device.
