Abstract
A color electrophotographic image forming apparatus includes a main body, cartridge support, an engaging portion, and a pressure member. The support supports a plurality of cartridges and moves between a first position in the main body and a second position for mounting and detaching the cartridges. The engaging portion is provided to one of the support and the main body at a position corresponding to the second position for at least one cartridge. The pressure member is provided to the other and is elastically urged to disengageably engage the engaging portion. When the support moves from the first to the second position, a load required for movement of the support at the second position is larger than a load required for the movement at other positions than the second position, by engagement of the pressure member with the engaging portion.
