A color electrophotographic image forming apparatus including: a cartridge supporting member supporting a plurality of cartridges and moving between an inside position in the main body and a mounting and detaching position for mounting and detaching the cartridges; 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, wherein 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 the movement at other positions than the mounting and detaching position, by engagement of the pressure member with the engaging portion.
