An image forming apparatus is provided. The image forming apparatus includes plural cartridges and a cartridge holder which integrally supports cartridges and is movable in an alignment direction of the cartridges between an outer position and an inner position relative to the apparatus main body. Each cartridge includes a developer carrier, a handle member which is displaceable between a protrusion position of protruding upward and a retreat position below the protrusion position, and a cover member which is displaceable between a close position of covering an upper part of the developer carrier and an open position of opening the upper part of the developer carrier. At least the cartridges are provided with an interlocking mechanism which is configured to displace each of the handle members and the cover members in conjunction with moving the cartridge holder with respect to the apparatus main body.
