Abstract
A color electrophotographic apparatus arranged as follows is disclosed. A plurality of image forming units (1BK, 1C, 1M, 1Y) each including a developing device having an electrostatic latent image holding member and toner of a different color are employed. Each of the image forming units is arranged to be displaceable so as to be moved to the same image forming position for positioning. At the image forming position, the image forming unit is exposed to light image by an exposure device for image formation, with its toner image being transferred onto a transfer material through a confronting transfer transport device. The image forming unit at the image forming position is sequentially exchanged, and by the reciprocation of the transfer material through the transfer/transport device, toner images of respective colors are transferred as overlapped through positioning for coincidence, onto the same transfer material.
