ABSTRACT:
An endless imaging web is supported by a large diameter drum and at least one small diameter roller. First and second electrostatic images are created and toned on the same portion of the web as it is backed by the drum. The toners are of different color to create a multicolor image on the imaging web. The multicolor image is transferred to a receiving sheet, which receiving sheet is separated from the web as the web passes around the small diameter roller. Two small diameter rollers can be also provided which facilitate single-pass duplexing.
