Abstract

An image forming apparatus, having a casing, a drum unit including first and second lateral walls and first and second photosensitive drums, first and second cartridges supported by the drum unit, first and second operable members, is provided. The first operable member and the second operable member press the first developing cartridge and the second developing cartridge, respectively, in a direction from the first lateral wall toward the second lateral wall to move the first and second developing rollers from the respective contacting positions to respective separated positions. The casing includes a restrictive portion. When the drum unit is attached to the casing, the restrictive portion restricts movement of the drum unit causable by at least one of a pressing action of the first operable member to press the first developing cartridge and a pressing action of the second operable member to press the second developing cartridge.
