Reproduction apparatus for producing simplex or duplex copies. A plurality of individual reusable photoconductive members are provided in a supply and are sequentially transported around a path back to the supply. Positioned along the path are charge, expose, development, transfer and cleaning stations. In the simplex mode, first toner images are sequentially formed on photoconductive members transported around the path and sequentially transferred at the transfer station to first sides of copy sheets brought into transferable relationship with the photoconductive members. In the duplex mode, first and second toner images are formed on first and second photoconductive members respectively transported around the path and the toner images are transferred at the transfer station to opposite sides of a copy sheet brought into transferable relationship with the first and second photoconductive members.In either mode, the copy sheets and photoconductive members are separated, the toner image(s) fixed to the copy sheet and the photoconductive members returned to the supply for reuse.
