  • Patent number: 8744334
    Abstract: The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image, a development station for applying toner particles to said latent image which forms a developed toner image, and a transfer station for transferring said developed toner image from the primary imaging member to a receiver. A fuser assembly is included for fixing the developed toner image to the receiver, to form a fused toner image on the receiver. An endless transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing porous layer that would tribocharge positively upon contact with negatively charged toner particles, and a porous overcoat outermost layer that does not tribocharge positively upon contact with negatively charged toner particles.

  • Patent number: 7973103
    Abstract: The present invention discloses a fuser roller composition that contains a fluorocopolymer, an aliphatic ketone organic solvent, metal oxide particles, and a benzyltriphenylphosphonium phenolate salt curing agent. To this composition is added a sufficient amount of 4,4?-(hexafluoroisopropylidene) diphenol to extend a time at which viscosity of the composition rises above a predetermined level.

  • Patent number: 7252873
    Abstract: A method for forming a receiver transport member for an electrostatographic reproduction apparatus. The transport member transports receiver members with respect to a fuser assembly and is frictional coupled to a transfer member for driving the transfer member. The method for forming the transport member provides a substrate bearing a high friction layer that includes inorganic particles, with a compound of aluminum selected from the group consisting of aluminum hydroxide, alumina hydrate, aluminum oxide, pseudo-boehmite, boehmite alumina, aluminum salts, and mixtures thereof, dispersed in an organic binder so that the high friction layer is capable of preventing a loss of frictional coupling due to release oil applied to a receiver member bearing a fused toner image.

  • Publication number: 20040265487
    Abstract: A method for applying a seamless coating of a surface-modifying material to a product roller by transfer of the material to the product roller, from an application roller, to produce the seamless coating. Gravure rollers, slot dies, falling curtains or ribbons, jets and sprays may be used to deposit the material on the product roller. Dipping may also be used. Gravure rollers are preferred as the application roller. The coating is applied as a plurality of coatings, which are applied without drying the previous coating before application of a subsequent coating.
