Abstract
An image forming apparatus includes an image carrier, a driving unit for transmitting a driving force to the image carrier via a driving spline, and a plurality of members to be driven for driving the driving force transmitted from the driving unit via the image carrier. A shaft is disposed coaxially with a rotation shaft of the image carrier in one end of the image carrier. An involute spline-shaped follower spline to which the driving force is transmitted from the driving unit via the driving spline is formed on an inner peripheral surface of the flange, and a driving force transmitter for transmitting the driving force to at least one of the member to be driven is formed on an outer peripheral surface of the flange.
