Abstract
A color electrophotographic image forming apparatus is disclosed. The apparatus includes a cartridge supporting member supporting a plurality of cartridges and moving between a position inside a main body of the apparatus and a mounting and detaching position for mounting and detaching the cartridges. The apparatus further includes an engaging portion provided to one of the supporting member and the main body at a position corresponding to the mounting and detaching position for at least one cartridge, and a pressure member provided to the other and elastically urged to disengageably engage with the engaging portion. When the supporting member is moved from the inside position to the mounting and detaching position, a load required for movement of the supporting member at the mounting and detaching position is made larger than a load required for movement at other positions than the mounting and detaching position.
