Abstract

A primary imaging member, for example, a photoconductive web is used to form a series of primary toner images. Each toner image in the series is transferred to a separate secondary imaging member. The secondary image members can be drums covered by blank master sheets. Masters are formed on the secondary imaging members defined by the primary toner image. For example, the primary toner images can be fused to the master sheets to form xeroprinting masters. The masters are used to form transferable color images that are transferred back to the primary imaging member in registration to form a multicolor image. The multicolor image can be transferred to a receiving sheet.
