ABSTRACT:
In an electrographic reproduction apparatus having a single process assembly for forming transferable images on a member moving along an image travel path, a mechanism for producing duplex copies on receiver sheets moving along a travel path spaced relative to such image travel path. Such mechanism includes a pair of similar doner rollers. The first doner roller is operatively associated with the transferable image-bearing member and located adjacent to one side of the sheet travel path for selectively receiving a transferable image from such member and transferring such image to one side of a receiver sheet moving along the sheet travel path. The second doner roller is operatively associated with the transferable image-bearing member and located adjacent to the opposite side of the sheet travel path for selectively receiving a transferable image from such member and transferring such image to the opposite side of such moving receiver sheet, whereby a duplex copy is produced.
