Abstract
Xeroprinting is performed without fusing a master toner image. A master toner image is made by conventional electrophotography, for example, by charging, imagewise exposing and applying toner to a photoconductive imaging member to create a first toner image. The first toner image is charged with charges of a first polarity opposite that of the toner image and the member is erased with erase illumination through its base. This creates a toner image with a charge opposite that of the original toner image which is tightly held by opposite charges which have migrated to the portion of the electrophotosensitive member just under the toner. The imaging member is then toned again with toner of the same polarity as the original toner to create a second toner image that overlies the first toner image. The imaging member is again erased through its base, and the second toner image is transferred to a receiving sheet without disturbing the first toner image. The toner image may then be used as a master to repeat the process but without the necessity of creating the master toner image again.
