    摘要： An electrode wire for a hybrid scavengeless developer unit is electrostatically coated with a conductive coating comprised of a crosslinked polymer and a conductive material. The wire is coated by first electrostatically coating the wire with a coating composition including a crosslinkable polymer and a conductive material. Following electrostatic application of the coating, the coated wire is initially heated to a temperature above the melt temperature of the crosslinkable polymer and below the crosslinking temperature of the polymer for a time sufficient to permit the at least one polymer to flow out over the surface of the wire, and then further heated by increasing the temperature of heating above the crosslinking temperature of the polymer for a time sufficient to crosslink the polymer. A tough, substantially smooth coated electrode wire is achieved that, when used in a hybrid scavengeless developer unit, exhibits little to no buildup of toner or toner components on the surface of the wire, thereby eliminating image quality defects that might otherwise be caused by such buildup.

    摘要： A process for the preparation of conductive, electronegative, submicron polymeric particles comprised of a first polymer optionally containing from about 1 to about 50 percent by weight of a conductive filler and a second electronegative, contrast polymer, and wherein said conductive polymer particles with optional filler are prepared by mixing at least one monomer with a polymerization initiator, a crosslinking component and a chain transfer component; effecting bulk polymerization until from about 5 to about 50 weight percent of the monomer has been polymerized; terminating polymerization by cooling the partially polymerized monomer; adding thereto from about 1 to about 50 weight percent of a conductive filler or conductive fillers, followed by mixing thereof; dispersing the aforementioned mixture of conductive filler or fillers, and partially polymerized product in water containing a stabilizing component to obtain a suspension of particles with an average diameter of from about 0.05 to about 1 micron in water; polymerizing the resulting suspension by heating; adding a second contrast polymer emulsion, suspension or fine dispersion with high shear mixing; and optionally subsequently washing and drying the polymer particles obtained.

    摘要： Carrier particles comprise a core and a polymer coating that comprises a mixture of polymethyl methacrlyate (PMMA) and melamine. The coating compositions comprise from about 60 to about 80 percent by weight of PMMA and from about 20 to about 40 percent by weight of melamine. The carriers may be combined with a toner to provide a developer suitable for use in an electrostatographic process. Carriers comprising the PMMA/melamine coatings exhibit increased triboelectric charging, a more conductive carrier, and also contribute to reducing toner cohesion.
