    摘要: A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method comprises the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit comprising a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further comprises contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.

Toner particles are then formulated in the hydrocarbon reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that is different from the reaction solvent, wherein the carrier liquid comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL, to form a redispersed liquid electrographic toner composition. Preferred carrier liquids are silicone oils. Products and kits are also provided.
