Abstract:
A process unit includes a photosensitive member that carries an image; a developing device that has a developer carrying member carrying a developer to be supplied to the photosensitive member; a rotating shaft that supports the developing device rotatably for approaching and separating from the photosensitive member; a photosensitive member gear provided to the photosensitive member; and a developing gear provided to the developer carrying member. The photosensitive member gear and the developing gear engage together and driving force can be transmitted, and the rotating shaft is placed on a driving force vector between the gears or on an extended line thereof, the driving force vector being generated from engagement between the photosensitive member gear and the developing gear.
