Abstract
An image forming apparatus includes image forming portions for forming images on a photosensitive member with different color developers by developing rollers. Developing roller moving mechanisms include (i) a developing roller moving member for moving one of the developing roller between a first contacting position contacting an associated photosensitive member and a first separating position separated from the associated photosensitive member and (ii) a first driving force switch for switching between a first transmission state in which a driving force is transmitted to the developing roller moving member to move the developing roller of an image forming portion and a disconnected state in which the transmission of the driving force is disconnected. Driving forces transmitted to the developing roller moving members are supplied from first and second gear trains.
