ABSTRACT:
An image forming apparatus includes a cartridge including an electrophotographic photosensitive member, a developing roller, a spacer movable between spacing and contacting positions for spacing apart and contacting the roller and member, and a receiver receiving a force spacing the roller from the member. The apparatus includes a mounter detachably mounting the cartridge, an abuter retracting the spacer from the spaced position when the mounter mounts the cartridge with the spacer at the spaced position, and a function member movable between a first position spacing the roller from the member by abutting the receiver with the cartridge mounted to the mounter and a second position contacting the roller to the member. When the mounter mounts the cartridge with the spacer at the spaced position, the abuter abuts the spacer retracting it from the spaced position after insertion so that the function member taking the first position abuts the receiver.
