摘要： An apparatus for applying an electrical charge to a charge retentive surface, wherein a bias contact roll member is situated in contact with a surface of the photoreceptor. The bias contact roll member is supplied with an electrical bias including an oscillating voltage signal having a DC offset, wherein the oscillating voltage is clipped via a rectifier circuit to remove a predetermined polarity component thereof.

摘要： An electrostatographic imaging member assembly comprising a hollow electrostatographic imaging drum having a first end and a second end, at least one coating on the drum extending from the first end of the drum to the second end of the drum, the coating having an outer electrostatographic imaging surface, drum supporting hubs mounted on the first end of the drum and the second end of the drum, the drum supporting hubs comprising a disk shaped member comprising a disk shaped segment having an exposed annular landing strip surface parallel to and flush with the electrostatographic imaging surface, the annular landing strip surface having a width of at least about 3 millimeters and having an imaginary axis coextensive with an imaginary axis of the drum. The electrostatographic imaging member assembly may be utilized in electrostatographic imaging apparatus in which the hubs support electrostatographic imaging apparatus subassembly components. The electrostatographic imaging member assembly is fabricated by coating the entire external surface of the substrate and mounting the hubs to the ends of the resulting coated substrate.
