    摘要： There is provided an electrophotographic element and method of making the electrophotographic element comprising a conductive support, a charge generation layer and a charge transport layer, said electrophotographic element having thereon a protective layer of a fluorinated diamond-like carbon wherein the fluorine content of the outermost surface of the fluorinated diamond-like carbon layer is between about 25 and about 65 atomic percent based on the total composition of the outermost surface of the protective layer. The protective layer provides for a low surface energy coating having a long process lifetime without causing latent image spread or degradation of photosensitivity.

    摘要： A process for reducing image defects in an electrostatographic image resulting from particulate contamination. A primary imaging member, including a photoconductive element and an outermost layer of silicon carbide, is uniformly charged in an electrostatographic imaging apparatus subject to particulate contamination. The electrostatographic imaging apparatus includes a charging station, an exposing station, at least one developing station, and a transfer station comprising an electrically biased roller transfer assembly. The primary imaging member is exposed imagewise at the exposing station to form a latent image on the imaging member, which is thereafter developed with toner at the developing station to form a developed image on the imaging member. The primary imaging member bearing the developed image is passed through a charge erasing station to remove residual surface charge, then contacted with a receiver by the electrically biased roller transfer assembly, causing the developed image to transfer to the receiver. The silicon carbide layer protects the photoconductive element against damage by contaminant particles present in the apparatus.
