摘要： 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.

摘要： A method of cleaning an aluminum drum substrate that removes cutting chips, and degreases to remove high viscosity drawing oil used in a cold drawing process, without using a chlorine-containing organic solvent. A plurality of aluminum drum substrates are arranged in rows, with an axis of each drum substrate being vertical and parallel with the axis of the other drum substrates. A cleaning liquid is ejected at a predetermined ejection pressure from a high-pressure cleaning nozzle. The cleaning liquid is ejected in a fan shape having a predetermined spread angle and from above a top opening of one of the drum substrates towards the drum substrate. While ejecting the cleaning liquid, the nozzle is horizontally and sequentially traversed above openings of the other drum substrates in a direction of the row, while swinging the nozzle in the direction of the row.

摘要： A conductive substrate of an electrophotographic photoconductor has magnesium suicide precipitated therein as an impurity compound. The conductive substrate has an aluminum oxide film of minimum thickness deviation, and an aluminum base which exhibits a light scattering effect. An electrophotographic photoconductor using such a conductive substrate suppresses interference fringes caused by the interference action of a semiconductor laser light. Furthermore, irregular printing density and the formation of black spots is eliminated. A method for making such a conductive substrate includes annealing an aluminum base doped with silicon and magnesium to precipitate out Ms2Si, followed by anodizing a surface of the aluminum base to form an aluminum oxide film. A charge generation layer and a charge transport layer are formed on the aluminum oxide film to complete the electrophotographic photoconductor.
