Abstract
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.
