WET ELECTROPHOTOGRAPHIC TONER COMPOSITION, METHOD FOR MANUFACTURING THE SAME, AND METHOD FOR FORMING ELECTROPHOTOGRAPHIC IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a wet electrophotographic toner composition capable of transferring an image from the surface of a photoconductor to an intermediate transfer material or to a printing medium suitably without forming a film on the photoconductor. SOLUTION: The wet electrophotographic toner composition contains: (a) a liquid carrier having <30 mL kauri-butanol number; and (b) a plurality of toner particles dispersed in the liquid carrier. The toner particles contain a polymer binder including at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The toner composition contains sufficient hydrogen coupling functional groups to provide a three-dimensional gel having controlled rigidity which can be reversibly changed into a fluid state by addition of energy. The toner composition does not form a film under photoreceptor image formation conditions. COPYRIGHT: (C)2005,JPO&NCIPI
