Abstract:
A cartridge has a first frame supporting a photosensitive member and a second frame supporting a developer carrying member. The first and second frames can take either a contact position where the two members are in contact with each other or a separated position where the two members are separated. A supporting member supporting the cartridge is movable between a mount position in a housing and a pull-out position outside the housing. When the supporting member is held in the pull-out position, the first and second frames are retrained in the separated position. The cartridge is supported on the supporting member to be movable between a first position where image formation is disabled and a second position where image formation is enabled. The cartridge is moved from the first position to the second position attendant to the movements of the supporting member from the pull-out position to the mount position.
