ABSTRACT:
An ionographic imaging member has a conductive layer overcoated by a charge accepting layer. Overcoating layers of acrylate, polycarbonate, polyester, polyurethane, acrylic homopolymer or copolymer and the like are provided. Blocking layers may be provided for preventing charge injection and reducing surface charge decay and bulk charge trapping. The charge accepting layer may be doped with a charge clocking material for preventing charge injection. The overcoating and blocking layers may be one and the same.
