  • Oil-less fuser member
    Patent number: 7242900
    Abstract: A fuser member includes a substrate and an outer layer comprising a polymeric material, wherein the polymeric material is post-halogenated to provide a post-halogenated polymeric material. The fuser member is advantageously used without a release oil applied to the outer layer.

  • Lathing and cleaning process for photoreceptor substrates
    Patent number: 5346556
    Abstract: A method of cleaning a substrate includes:(1) lathing a substrate surface with a cutting fluid composition containing (A) an antioxidant, (B) a surfactant, (C) a lubricant, and (D) water;(2) rinsing the lathed substrate surface with high quality deionized water having a resistivity of at least 2M ohm-cm;(3) immersing the rinsed lathed substrate surface in a bath of high quality deionized water having a resistivity of at least 2M ohm-cm; and(4) removing the substrate from the bath of deionized water at a rate low enough to prevent water droplets from forming on the substrate.
