ABSTRACT:
The present invention relates to an electrophotographic photoconductor comprising a photoconductive layer, a protective layer, and a conductive support, wherein the protective layer is disposed as the outermost layer of the photoconductive layer, and 20% by volume to 60% by volume of fine particles of fluorine-contained resin and at least one compound selected from amine aromatic compounds and hydroxy aromatic compounds are incorporated into the protective layer.According to the present invention, high durability may be achieved, image degradation such as lags may be controlled from the increase of residual potential and decrease of charging, and high quality images may be formed stably even after the prolonged and repeated usage.The present invention also relates to an electrophotographic process, an electrophotographic apparatus and a process cartridge for the electrophotographic apparatus which utilize the electrophotographic photoconductor respectively.
