PROBLEM TO BE SOLVED: To provide means that increases immersion speed without causing liquid drip even in a coating liquid with high concentration, in a method for forming a photoreceptor by immersing a cylindrical substrate for electrophotographic photoreceptor into a coating liquid.SOLUTION: A coating tank, an overflow tank, and coating liquid circulation means are provided. The coating tank includes a coating tank body, and a taper structure part 2 that decreases in diameter toward an overflow surface from the coating tank body. Immersion coating is carried out under the condition in which the difference D-d between the outer diameter d (mm) of the cylindrical substrate and the diameter D (mm) of the circle equal in area to the overflow surface with the inner diameter of the coating tank, which is the leading end of the taper structure part 2, is 4 mm or less. |
