Image holding member and apparatus making use of it

The present invention provides a process for producing an electrophotographic photosensitive member through application of a paint by dipping an object to be coated into a paint coating bath. The process comprises steps of: blowing a gas periodically into the paint from a lower portion of the paint coating bath agitate the paint, and dipping the object to be coated at a predetermined time after agitating the paint.
