Abstract: An electrophotographic photoconductor is disclosed, which comprises an electroconductive support, a photoconductive layer formed on the electroconductive support, and an overcoat layer formed on the photoconductive layer, in which the overcoat layer comprises a binder resin and one component selected from the group consisting of a crown ether, a polyalkylene glycol, a polyalkylene glycol ester and a polyalkylene glycol ether. The overcoat layer may be composed of an intermediate layer formed on the photoconductive layer, and a protective layer formed on the intermediate layer in such a manner that any of the crown ether and polyalkylene glycol derivatives is contained in the intermediate layer.

Abstract: An electrophotographic photoconductor is disclosed, which comprises an electroconductive support, an undercoat layer formed on the electroconductive support, comprising at least one metal oxide selected from the group consisting of zirconium oxide, magnesium oxide, calcium oxide, beryllium oxide and lanthanum oxide, and a photoconductive layer comprising a charge generating layer and a charge transporting layer, formed on the undercoat layer.
