  • Carrier particles
    Patent number: 6511780
    Abstract: Carrier comprised of a mixture of insulating carrier particles and conductive carrier particles.
    Type: Grant
    Filed: July 30, 2001
    Date of Patent: January 28, 2003
    Assignee: Xerox Corporation
    Inventors: Richard P. N. Veregin, Vladislav Skorokhod, Michael S. Hawkins
  • Method of making a conductive micro-powder resin
    Patent number: 6361915
    Abstract: A process for manufacturing a conductive micro-powder includes the steps of: (i) forming an aqueous dispersion of conductive material and the first surfactant, (ii) mixing a latex emulsion of a polymer and a second surfactant into the aqueous dispersion to form a suspension and (iii) recovering the conductive micro-powder from the suspension. The first and second surfactants are of the same class and polarity. The conductive micro-powder finds particular utility as a coating for carrier core particles, and as a conductive coating component of carrier particle coatings.
    Type: Grant
    Filed: November 28, 2000

  • Micro-powder coating for xerographic carrier
    Patent number: 6355391
    Abstract: A micro-powder includes: (i) a sub-micron sized powder recovered from a synthetic latex emulsion of polymer and surfactant; (ii) a conductive filler incorporated into the powder; and (iii) optional charge enhancing additives incorporated into the powder. The conductive micro-powder finds particular utility as a coating for carrier core particles of toner and developer compositions.
