ABSTRACT:
In m.sub.1 magnification copy mode, a photosensitive member, at the first exposure station is exposed to the light image of an original existing at the first illumination position through a first lens array. In m.sub.2 magnification copy mode, the photosensitive member, at the second exposure station, is exposed to the light image of the original existing at the second illumination position through a second lens array. The original is moved through the first and second illumination positions in sequence while the photosensitive member is moved through the first and second exposure stations in the order named. Registration rollers for feeding transfer materials to a transfer station is operated with different timings in the m.sub.1 magnification and m.sub.2 magnification modes, these timings being different from each other by a period of time which corresponds to the spacing between the first and second exposure stations.
