Abstract
An image forming apparatus includes a photosensitive unit and a developing unit, at least one of which is arranged rotatable about a parallel support shaft. In a state that the both units are mounted on an apparatus main body, a developing roller gear (driven gear) of the developing unit is in mesh with a drive gear provided on the photosensitive unit. A drive force is transmitted from the drive gear to the developing roller gear. The developing roller gear and the drive gear are arranged such that a drive force acting on a pitch point has an extension line passing through a center of the parallel support shaft.
