Abstract
An image forming apparatus includes a main assembly and a transfer unit. A rotatable first coupling is provided in the main assembly and is rotatable by a driving source. The transfer unit is detachably mountable to the main assembly and is movable in a first direction when dismounted from the main assembly. The transfer unit includes a movable belt and a rotatable second coupling capable of receiving a driving force from the first coupling. The first direction is parallel with a traveling direction of the belt. One of the first and second couplings is movable in a second direction perpendicular to the first direction. When the transfer unit is dismounted from the main assembly, one of the first and second couplings is moved in the second direction to retract from the other coupling, by the transfer unit being moved in the first direction with the first and second couplings being kept in contact with each other.
