PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of surely suppressing the occurrence of an image unevenness to such a degree that the image unevenness is not visually recognized. SOLUTION: The image forming apparatus 1 is provided with an image forming section 2 which has a flanged electrophotographic photoreceptor 3 obtained by fastening flanges 14a, 14b to both end openings in an electrophotographic photoreceptor 13 having a photosensitive layer formed on a cylindrical substrate 19 by a dip coating method, and in which an image formed on the flanged electrophotographic photoreceptor 3 is transferred onto an image output medium 12 to form a black-and-white image, the image forming apparatus 1 achieves resolution R (dpi), and the absolute valueΔt (μm) of film thickness difference between the maximum and minimum film thicknesses of a coating film 61 on the inside face of the electrophotographic photoreceptor 13 satisfiesΔt≤1,000÷R<SP>0.5</SP>. In this case, with respect to an image formed using the image forming apparatus 1, the occurrence of image unevenness can be surely suppressed to such a degree that image unevenness is not visually recognized.
