Abstract:
A method of producing an electrophotographic photosensitive member comprising the steps of:providing a cylindrical substrate for the electrophotographic photosensitive member by cutting and mirror finishing an aluminum alloy substrate having a total content of Fe+Si+Cu within a range of 0.001 to 1% by weight;cleaning the cylindrical substrate by ejecting at least one cleaning liquid selected from the group consisting of pure water, pure water having dissolved carbon dioxide, and pure water containing a surface active agent from a plurality of nozzles at an ejection pressure from at least 5 kgf/cm.sup.2 to at most 50 kgf/cm.sup.2 such that those surfaces of the cleaning liquid ejected from the respective nozzles which are in contact with a surface of the cylindrical substrate do not interfere with each other and the ejection occurs along a longitudinal axis of rotation of the cylindrical substrate, said longitudinal axis being vertically oriented; andforming a functional film comprising a non-monocrystalline material comprising silicon atoms as a main component on the surface of the cylindrical substrate by plasma CVD.
