Abstract:
A method of producing an electrophotographic photosensitive member comprising the steps of:forming a functional film composed of an amorphous material containing a silicon atom as a major component on a surface of an aluminum substrate by a vacuum vapor phase growth method; andspraying water on said surface of said substrate from nozzles before said functional film is formed on said surface;wherein the nozzles for spraying water on the substrate surface comprise first and second nozzle groups each of which comprise at least two nozzles arranged at equal intervals wherein said first and second nozzle groups are each concentrically arranged on a separate circle, and wherein the nozzle groups have a twisted positional relationship between them, and wherein said twisted positional relationship is that said nozzles of said second nozzle group are differently positioned from said nozzles of said first nozzle group in an axial direction with respect to a circle face of a cylindrical substrate.
