Abstract
An apparatus for transferring a developed image from a photoconductive surface to a copy sheet in a transfer zone is disclosed. The apparatus includes a mechanism for directing a flow of gas onto the copy sheet in the transfer zone to urge the copy sheet toward the developed image on the photoconductive surface so as to enhance contact between the copy sheet and the developed image in the transfer zone. The apparatus further includes a mechanism for charging the copy sheet in the transfer zone, after the gas directing mechanism directs the flow of gas onto the copy sheet, to attract the developed image from the photoconductive surface to the copy sheet. Also disclosed is a method of transferring a developed image from a photoconductive surface to a copy sheet in a transfer zone. The method includes the step of directing a flow of gas onto the copy sheet in the transfer zone to urge the copy sheet toward the developed image on the photoconductive surface so as to enhance contact between the copy sheet and the developed image in the transfer zone. The method further includes the step of establishing, in the transfer zone and after the gas directing step, a transfer field that is effective to attract the developed image from the photoconductive surface to the copy sheet.
