ABSTRACT:
An apparatus which transfers a developed image from a photoconductive surface to a copy sheet. The apparatus includes a corona generating device arranged to charge the copy sheet. This establishes a transfer field that is effective to attract the developed image from the photoconductive surface to the copy sheet. A sheet guide, adapted to have a portion thereof contiguous with the corona generating device, maintains the copy sheet substantially wrinkle free as it is being guided into contact with the photoconductive surface in the transfer field.
