ABSTRACT:
An apparatus which transfers a developed image from a photoconductive surface to a copy sheet. The apparatus includes a corona generating member arranged to charge the copy sheet. This establishes a transfer field that is effective to attract the developed image from the photoconductive surface of the copy sheet. A rotatable helical element surrounds the corona generating member and is positional to contact the copy sheet and press it into contact with at least the developed image on the photoconductive surface to eliminate transfer deletions that are caused by non-contact between the photoconductive surface and a copy sheet during the transfer step.
