Abstract
The present invention provides a method of producing an electrophotographic photosensitive member capable of obtaining high-quality uniform images without image defects and nonuniformity in image density. The method of producing an electrophotographic photosensitive member includes a step forming a functional film on a substrate, and a washing step of spraying water on the substrate surface from concentrically arranged nozzle groups positioned in a twisted relationship before the step of forming the functional film.
