Abstract

A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.
