An image forming apparatus includes multiple image bearers, multiple image bearer gears, a drive source, an output gear, a drive transmission body, multiple relay gears, and multiple drive gears. A center of rotation of each of the multiple drive gears to which a driving force is transmitted from the drive source is located downstream from a corresponding one of the multiple relay gears in a rotation direction of the corresponding one of the multiple relay gears, relative to a virtual line segment connecting a center of rotation of the corresponding one of the multiple relay gears connected to the multiple drive gears and the center of rotation of a corresponding one of the multiple image bearer gears.
