Abstract (en)

[origin: EP0388342A2] An electrophotographic machine with a transfer corona generator (13) for producing ionic flow to the backside of print paper to electrostatically attach the paper to the photoreceptive image bearing surface (12). The machine includes a flexible support member (40-44) which is movably mounted to mechanically press the print paper against the photoreceptive surface within the transfer zone, preferably at or near the region of peak transfer charge distribution. In that manner, charge from the transfer corona attaches the print paper to the photoreceptive surface at the line of release from the mechanical pressure applied by the flexible support member and thereby eliminates voids in the transfer of toner to print paper caused by air gaps between the paper and the photoreceptive surface.
