1. An image forming apparatus, comprising:
a frame;
a shaft supported by the frame; and
a first coupler including:
a body coupled to one end of the shaft, the body having a first surface and a protrusion protruding from the first surface, wherein the protrusion is to lock with a groove of a second coupler of a cartridge to mount the cartridge to the frame,
wherein the shaft is to provide a rotational force to the first coupler in a first rotational direction to rotate the protrusion of the first coupler in the first rotational direction and to insert the protrusion into the groove of the second coupler to lock with the second coupler, and
wherein the first surface of the first coupler is to contact a second surface of the second coupler to transmit the rotational force to the second coupler in the first rotational direction.
