A method of producing an electrophotographic photoconductor, which prevents filler material in a coating liquid from aggregating onto etching pits formed on a surface of an aluminum raw drum. A photoconductor produced by the method of invention scarcely generates printing defects. The method includes steps of cutting a surface of an aluminum cylindrical substrate, degreasing and cleaning the surface of the aluminum cylindrical substrate with an aqueous detergent after the cutting step, and applying and forming a coating layer containing a filler material on the aluminum cylindrical substrate after the degreasing and cleaning step. Nickel concentration in the aluminum cylindrical substrate used in the method of invention is at most 50 ppm by weight.
