PROBLEM TO BE SOLVED: To provide a high-quality electrophotographic photoreceptor and its production method by which a photosensitive layer having uniform film thickness and film property can be formed on the outer surface of a substrate subjected to proper roughening treatment by simplified finishing process. SOLUTION: In this production method, a cylindrical conductive substrate 1 fixing to a rotating base bed 8 is rotated at a specified rotational speed around the cylinder axis, and a spray nozzle 8 provided with a spray port 7 which can move in the axial direction of the substrate while keeping specified distance from the outer surface of the substrate 1, an abrasive supply port 5a and a compressed air supply port 6a is disposed. In this state, specified abrasives 5 having >=500# grain size and compressed air 6 are supplied to respective supply ports to spray the abrasives 5 to the outer surface of the substrate 1 while the spray nozzle 7 is moved at a specified speed under specified blowing pressure to roughen the surface of the substrate to <=5μm max. roughness. Then a photosensitive layer is formed on the outer surface of the substrate.
