PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which is capable of reducing rubbing and vibration caused between a substrate and a flange, even when the electrophotographic photoreceptor is enlarged in size.SOLUTION: An electrophotographic photoreceptor 1 includes a cylindrical substrate 10, a photoreceptive layer 11 formed on the cylindrical substrate 10, and a flange 20 arranged at the end of the cylindrical substrate 10. The cylindrical substrate 10 includes a positioning part 12 for positioning to the flange 20 at the end thereof. The positioning part 12 includes a notch part 13 having a positioning surface 13a, a pair of first pressing parts 14 being movable in the circumferential direction of the cylindrical substrate 10 and coming into contact with a pair of positioning surfaces 13a respectively, to apply a pressing force in the circumferential direction of the cylindrical substrate 10, and a second pressing part 15 being movable in the axial direction of the cylindrical substrate 10 and coming into contact with each of the pair of first pressing parts 14, to apply the pressing force along the circumferential direction of the cylindrical substrate. |
