PROBLEM TO BE SOLVED: To make an electrophotographic photoreceptor suitable to be used in a contact electrification type copying machine. SOLUTION: This electrophotographic photoreceptor possesses a photoreceptive film formed on a base substance by immersing and coating. Then, the photoreceptive film possesses an image forming area and an electrification area covering the image forming area. The film thickness A of a part positioned at the lower part at the time of immersing and coating out of the outside part of the image forming area in the electrification area is larger than the film thickness B of an end positioned at the lower part at the time of immersing and coating in the image forming area. In such a case, it is desirable that a difference between the film thickness A and the film thickness B is larger than 0.3μm. A method in which the drawing-up speed at the time of coating the lower end of the electrification area is made hither than that at the time of coating the lower end of the image forming area in the case of forming the photoreceptive film by immersing and coating is adopted as the producing method of the photoreceptor.
