Abstract
To provide an electrophotographic photosensitive member manufacturing method capable of preventing a substrate from corroding in working of the substrate and obtaining a high-quality image free from image defects and image density unevenness, the method of manufacturing an electrophotographic photosensitive member comprises the step of forming a functional film made of an amorphous material on the surface of an aluminum substrate by reduced-pressure vapor deposition, wherein the surface of the substrate is cleaned with the water containing an inhibitor as a specific component before the step of forming an electrophotographic photosensitive member.
