ABSTRACT:
An image forming apparatus is provided. The image forming apparatus includes a main body; process cartridges, each including a photosensitive drum and a developing roller; a body frame including a abutment portions and projecting portions; fixing members configured to rotate to a locked state where the fixing members bring the process cartridges into abutment with the abutment portions and to an unlocked state where the fixing members are spaced apart from the process cartridges; spacing members which move to a spacing position where the developing rollers are spaced apart from the photosensitive rollers and a permissive position where the developing rollers are in contact with the developing rollers; and a translation member reciprocating in a straight line for displacing the fixing members between the locked state and the unlocked state and moving the spacing members between the spacing position and the permissive position.
