  • Photoreceptor with low surface energy overcoat
    Patent number: 5436099
    Abstract: An electrophotographic imaging member including a substrate, a charge generating layer, a charge transport layer, and an overcoat layer comprising a hole transporting hydroxy arylamine compound having at least two hydroxy functional groups, hydroxy terminated diorgano siloxane and a polyamide film forming binder capable of forming hydrogen bonds with the hydroxy functional groups of the hydroxy arylamine compound and the hydroxy terminated diorgano siloxane.

  • Brush-based carrier bead removal device for a developer housing in a xerographic apparatus
    Patent number: 5216467
    Abstract: A device prevents the migration of particles from the edge of a moving surface, such as a photoreceptor in an electrophotographic printing apparatus. A brush in contact with an edge of the surface includes fibers of a first type, and fibers of a second type. The fibers of the second type are less resilient than those of the first type and substantially incapable of abrading the surface. The brush guides the particles toward a bead-removal device.
