1. An image forming apparatus comprising:
a housing having a front surface formed with an opening, and a rear surface opposite to the front surface in a front-rear direction of the housing;
a drawer movable through the opening in the front-rear direction between
an inner position where the drawer is accommodated within the housing, and
an outer position where a portion of the drawer is exposed to an outside of the housing; and
a process cartridge attachable to and detachable from the drawer, the process cartridge comprising
a drum cartridge comprising
a photosensitive drum, and
a drum frame supporting the photosensitive drum, and
a developing cartridge attachable to and detachable from the drum cartridge and configured to supply toner to the photosensitive drum,
wherein, in a state where the developing cartridge is attached to the drum cartridge, the developing cartridge is movable relative to the drum cartridge between
a first position where the developing cartridge is detachable from the drum cartridge, and
a second position where the developing cartridge is supported so that the developing cartridge can supply toner to the photosensitive drum, and
wherein, in a state where the process cartridge is supported by the drawer, the process cartridge is oriented relative to the drawer such that the first position of the developing cartridge is closer to the rear surface of the housing than the second position of the developing cartridge is to the rear surface of the housing in the front-rear direction.
