ABSTRACT:
A protection cover includes a cover base that covers and protects an external exposure portion of a photosensitive member and that comes into contact with an image forming apparatus housing body to movably guide a process cartridge; an extrusion member that is disposed in the cover base on a side opposite to an insertion direction of the process cartridge to the image forming apparatus housing body and that moves in the insertion direction of the process cartridge to extrude the process cartridge from the cover base; and a restriction portion that is disposed in the extrusion member to restrict the process cartridge in the cover base in a state where the process cartridge is located in the cover base and to release the process cartridge from the cover base in a state where the process cartridge is inserted and mounted to the image forming apparatus housing body.
