Abstract
An image forming apparatus includes an apparatus body and a detachable unit to be attached to the apparatus body in an attachment direction and detached from the apparatus body in a detachment direction. The detachable unit includes a rotary body and a unit drive gear. The apparatus body includes an apparatus-body drive gear to engage with the unit drive gear of the detachable unit attached in the apparatus body, at an engageable position on a downstream side of the apparatus-body drive gear in the attachment direction. One or each of the unit drive gear and the apparatus-body drive gear moves to a retracted position at which the one or each of the unit drive gear and the apparatus-body drive gear does not engage with the other of the unit drive gear and the apparatus-body drive gear and does not interfere with attachment and detachment operations of the detachable unit.
