ABSTRACT:
An endless transfer web is supported by a large diameter drum and at least one small diameter roller. Two or more imaging drums are positioned in transfer relation to the transfer web where it is backed by the large drum. Different color toner images are transferred in registration to the web to form a multicolor image which is transferred to a receiving sheet. The receiving sheet is separated from the web as the web passes around the small roller. The imaging drums can be electrophotosensitive drums with separate electrophotographic stations or drums which hold masters, for example, xeroprinting masters on their periphery.
