Abstract
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.
