  • Patent number: 4666780
    Abstract: A recording member comprising a conductive substrate having a dielectric coating thereon. The recording member is particularly useful with the electrographic recording process and apparatus described in U.S. Pat. No. 3,816,840. The dielectric coating exhibits charge dissipation properties that will allow removal and replacement of toner powder within one operating cycle of the aforementioned recording process, and the surface of the coating is sufficiently durable to allow the recording member to be used repeatedly, e.g., at least about 100,000 cycles, before the conductive substrate needs to be recoated.
