Abstract
An image forming apparatus includes an apparatus body including a drive source, a rotary member, and a first coupling movable in an axial direction with respect to the rotary member, and a unit attachable to and detachable from the apparatus body, the unit including a second coupling configured to receive the driving force by engaging with the first coupling. The rotary member includes an abutting portion. The first coupling includes an abutted portion configured to be abutted with the abutting portion, and is configured to rotate in the first rotation direction together with the rotary member in a case where the abutting portion presses the abutted portion. The apparatus body further includes a first urging member configured to urge the first coupling in a second rotation direction opposite to the first rotation direction.
