ABSTRACT:
An electrostatographic apparatus for providing images on a receiver, including an electrostatographic element movable along a path, having a substrate, an alloyed zirconia ceramic layer formed over the substrate and having an image receiving surface; and the image receiving surface of the alloyed zirconia ceramic layer being adapted to become electrically conductive when illuminated by a light source. The image receiving surface is illuminated with light in the pattern corresponding to an image so that the image receiving surface has electrically conductive and nonconductive portions which taken together represent the image. The image receiving surface is charged such that charge remains on the nonconductive portions of the image receiving surface. Toner particles are provided which adhere to the image receiving surface in the electrically conductive portions defining a developed image. Charged toner particles defining the developed image are transferred to the receiver and then the charged toner particles are fixed to the receiver.
