PURPOSE: To provide a photoreceptor device capable of easily separating a photoreceptor drum and a flange, for reusing. CONSTITUTION: The flange 1 is a stepped flange composed of a first cylindrical part 3 which has a diameter a little larger than the inside diameter of the photoreceptor drum 2 and is lightly press-fitted thereinto and a second cylindrical part, 4 which is confronted and brought into contact with the drum 2 on the peripheral end faces and has the outside diameter equal to that of the drum 2, the first and second cylindrical parts 3 and 4 are connected firmly by a thin layer connecting part C having a thin double cylinder and absorbs thermal expansion and shrinkage in an axial direction. The first cylindrical part 3 of the flange 1 is lightly press-fitted into the drum 2 on its end face side, the drum 2 and the second cylindrical part 4 face each other with contact on the peripheral end faces and a spring clutch 5 imparting tightening force to the peripheries of the second cylindrical part, 4 and the drum 2 in its rotational direction is disposed. Thus, the flange 1 can be separated from the drum 2 in the axial direction. |
