A method for manufacturing an electrophotographic photosensitive member capable of providing high quality even images, which are completely free from image defects and unevenness of image density, which comprises a step for forming a non-monocrystalline deposited film comprising silicon atoms and hydrogen atoms and/or fluorine atoms on an aluminum substrate containing a fine quantity of silicon atoms by a plasma CVD method, wherein the surface of the substrate is cleaned with water in which carbon dioxide has been dissolved before a process for forming the deposited film.
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.

The device for coating an element with a swab impregnated with a coating composition includes a mobile carriage bearing the swab wherein the carriage is movable along a guiding path, a member for pushing the swab towards the element to be coated so that a quality of the composition released from the swab coats the element, and a member for varying the release of the composition so that the coating is substantially uniform.
A device for coating an element is described. The device is capable of bearing and using a swab impregnated with a coating composition and includes a mobile carriage for bearing the swab. The carriage is movable along a guiding path. The device further includes an element for pushing the swab towards the element to be coated so that a quantity of the composition released from the swab coats an element. The device also includes an element for distributing the composition, so that the coating is substantially uniform.
A cleaning method for an electrophotographic photosensitive member that eliminate corrosion and cleaning irregularities of a substrate during cleaning, and a method of producing an electrophotographic photosensitive member which is easy to operate and capable of stably forming the photosensitive member at a low cost, in a high yield, and at a high speed. The cleaning method is a water-based cleaning method of cleaning a cylindrical substrate for an electrophotographic photosensitive member, using at least one selected from the group consisting of pure water, pure water having dissolved carbon dioxide, and pure water containing a surface active agent, wherein the cylindrical substrate is cleaned by a cleaning liquid ejected from a plurality of nozzles, and wherein 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 cleaning apparatus is arranged to carry out the cleaning method.
