Abstract
In a case where a cleaning member is located at a cleaning position in attachment of a process cartridge to an image forming apparatus, a stopper located at a first position butts against the process cartridge guided in a direction of attachment by a guide portion such that the process cartridge is disabled from being attached to the image forming apparatus, and in a case where the cleaning member is located at a retraction position in attachment of the process cartridge to the image forming apparatus, a lever portion moves due to a press by a cleaning unit and the stopper moves from the first position to a second position such that the process cartridge is enabled to be attached to the image forming apparatus.
