    摘要： A photoconductor for use in electrophotographic reproduction devices is disclosed. This photoconductor exhibits dramatically reduced end seal and paper area wear, as well as reduced positive electrical fatigue. The photoconductor of the present invention includes a low surface energy polyolefin wax, such as polyethylene or polypropylene, in relatively large particulate form having a mean particle diameter of from about 6 to about 12.mu., homogeneously dispersed in its charge transport layer.

    摘要： The present disclosure relates to an electrophotoconductive element comprising a conductive substrate, a charge generation layer including a charge generating compound and a charge transport layer. The charge generation layer includes a first polymer resin and second polymer resin to provide a blend including the charge generating compound. The first polymer resin may therefore indicate an energy at a half charge potential E0.5(POLYMER) upon exposure to light at a wavelength of about 350-500 nm. The blend then also indicates an energy at half charge potential E0.5(BLEND) upon exposure to light at a wavelength of about 350-500 nm. The second polymer resin of the blend is therefore selected to provide that E0.5(BLEND)

    摘要： This invention provides an organic photoconductor which does not experience end-seal wear in normal use. This invention provides charge transport formulation that is easily prepared and coated by standard, dip-coating methods. This is realized by addition of a small amount of poly(methyl methacrylate-co-ethylene glycol dimethacrylate). Commercially available, 8μ spherical particles are used. These microspheres are insoluble in common organic solvents, but are readily dispersed into polycarbonate-based charge transport formulations. A photoconductor roller is mounted in pressure engagement with two end seals, each on opposite side of the roller.
