PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor ensuring few image defects, having high sensitivity and high durability, causing no degradation of image quality in actual copying on a large number of sheets, free of deterioration of sensitivity due to film wear and faulty cleaning, and excellent in lubricity and mechanical properties by using a coating liquid excellent in stability and nearly free of generation of bubbles therein. SOLUTION: In the electrophotographic photoreceptor obtained by disposing a photosensitive layer on a conductive substrate, the photosensitive layer contains a copolymer comprising at least a repeating structural unit shown by formula [2-1] and a repeating structural unit shown by formula [2-5].
