An electrophotographic photoconductor comprises an electroconductive supporting material and a photoconductive layer containing a charge carrier producing pigment and a charge transporting material therein, which is formed on the electroconductive supporting material. As the charge carrier producing pigment, azo pigments and other materials which are known as the charge carrier producing pigments are employed. As the charge transporting material, anthracene compounds which are represented by the general formula 9-(R-CH=CH-), 10-X-anthracen are employed, wherein X represents H (hydrogen) or a halogen atom and R represents an unsubstituted phenyl radical, a substituted phenyl radial having a halogen substituent, a cyano substituent, a lower dialkyl amino substituent with one to four carbon atoms, a lower alkoxyl substituent with one to five carbon atoms, and nitro substituent, a napthyl radical, an anthryl radical, and a carbazoyl radical. In one embodiment of an electrophotographic photoconductor according to the present invention, the charge carrier producing pigment is dispersed in the photoconductive layer and in another embodiment of an electrophotographic photoconductor according to the present invention, the photoconductive layer essentially consists of a charge carrier producing layer and a charge transporting layer.
