    摘要： Dry electrographic toner compositions are provided comprising a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a wax associated with the dry toner particles, wherein substantially all of the wax is associated with the toner particle at the surface thereof. Methods of making electrographic toner compositions are also provided comprising preparing polymeric binder particles comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions, preparing toner particles, drying the toner particles, and milling the dry toner particles in the presence of a wax component to provide a dry toner particle composition having the wax associated with the toner particles. These toner compositions provide images having excellent durability and erasure resistance properties at low fusion temperatures and with little undesired offset.

    摘要： Methods of preparing a liquid electrographic toner composition are provided, wherein a polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions is first prepared in a hydrocarbon reaction solvent, wherein the hydrocarbon reaction solvent comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL. 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.

    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.
