ABSTRACT:
An electrophotographic photoconductor includes an electroconductive support; a photoconductive layer formed on the electroconductive support; and a surface protective layer formed on the photoconductive layer, the surface protective layer having a hydrogen-containing diamond-like carbon structure or amorphous carbon structure, which contains at least one additive element selected from the group consisting of nitrogen, fluorine, boron, phosphorus, chlorine, bromine and iodine, with the atomic ratio of the additive element to the carbon in the carbon structure having such a distribution in the direction of the thickness of the surface protective layer that the atomic ratio is smaller in the vicinity of the top surface of the surface protective layer and in the vicinity of the photoconductive layer adjacent to the surface protective layer than in the other portion of the surface protective layer.
