Abstract
A substrate for an electrophotographic photoconductor having an anodic oxidation film on the surface is subjected to two-step sealing treatment in which the substrate is sealing treated with nickel fluoride as a sealing agent, and then with nickel acetate as a sealing agent. Therefore, an electrophotographic photoconductor using the substrate for an electrophotographic photoconductor is small in charge potential difference between the first turn and the second turn and after, and does not generate a fogged image defect or the like even without preliminary charging before printing.
