  • Imaging members
    Patent number: 7291432
    Abstract: A photoconductive imaging member with linear and proportional collection efficiencies and substantially constant photoinduced characteristics comprised of a supporting substrate, and thereover in, for example, certain weight ratios, a single layer comprised of a mixture of a photogenerator component, a charge transport component, an electron transport component, and a polymer binder, and wherein the photogenerating component is a pigment.
    Type: Grant
    Filed: March 23, 2004
    Date of Patent: November 6, 2007
    Assignee: Xerox Corporation
    Inventors: Liang-Bih Lin, Surendar Jevadev, Markus R. Silvestri, James M. Markovics, Andronique Ioannidis, Linda L. Ferrarese, John S. Chambers, Anna M. Main
  • Uniform charge device with reduced edge effects
    Patent number: 7187534
    Abstract: By varying corona producing element height/projection, a more uniform charge potential is achieved. Elements, such as pins or teeth, are shorter at the edges of an element array and grow longer as one moves toward the center of the array. Such variation in height/projection overcomes shielding from adjacent teeth, as well as other effects, to yield the more uniform charging potential.
