  • Patent number: 7320853
    Abstract: 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 reaction solvent, wherein the 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 reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that has substantially the same chemical constitution as the reaction solvent to form a redispersed liquid electrographic toner composition. Products and kits are also provided.

  • Publication number: 20050141926
    Abstract: A method of producing a composite image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method includes steps for applying liquid transfer assist material comprising charged particles of transfer assist material to at least a portion of an element of the electrophotographic system, along with charged toner particles, in order to provide a composite image layer on a final image receptor through transfer of the composite image layer from another element in the system.

  • Publication number: 20050141928
    Abstract: A method of producing an image on a final image receptor in a single pass electrophotographic system is provided. The method comprises the steps of providing at least one toner development unit comprising a photoreceptive element and charged toner particles, and creating a toned image on the photoreceptive element that is transferred to an intermediate transfer member. The method further comprises providing a transfer assist material development unit for applying a transfer assist material to at least a portion of the toned image to form a complete image layer on the intermediate transfer member, wherein the complete image layer is formed in a single pass of the intermediate transfer member. The method also comprises contacting the complete image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the complete image layer to the final image receptor.

  • Publication number: 20050141927
    Abstract: 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.
