  • Overcoated charge transporting elements and glassy solid electrolytes
    Patent number: 5874018
    Abstract: Glassy solid electrolytes and charge transporting elements including antistatic elements and charge generating elements. The charge generating element has an electrically conductive layer, a charge generating layer overlying the electrically conductive layer, and a layer of glassy solid electrolyte overlying the electrically conductive layer. The glassy solid electrolyte includes a complex of silsesquioxane and a charge carrier. The complex has a surface resistivity from about 1.times.10.sup.10 to about 1.times.10.sup.17 ohms/sq. The complex has a T.sup.2 -silicon:T.sup.3 -silicon ratio of less than 1 to 1. The complex has a ratio of carbon atoms to silicon atoms of greater than about 1.2 to 1.
    Type: Grant
    Filed: June 25, 1997
    Date of Patent: February 23, 1999
    Assignee: Eastman Kodak Company
    Inventors: Wayne Thomas Ferrar, Jane Robin Cowdery-Corvan, Edward T. Miskinis, Catherine Newell, Donald S. Rimai, Louis Joseph Sorriero, John Anthony Sinicropi, David Steven Weiss, Nicholas Zumbulyadis

  • Method and apparatus for scavenging carrier employing a magnetic field and erase radiation
    Patent number: 5715503
    Abstract: Magnetic carrier particles are removed from a photoconductive image member by subjecting the carrier particles to a magnetic field while or after exposing the photoconductive image member to erasing radiation in the absence of a substantial electrical field affecting the carrier particles.
