PROBLEM TO BE SOLVED: To reduce the rotation unevenness of a rotor such as an image support in the constitution of supporting the rotor by reducing the number of part items to simplify the constitution, simplifying assembling to reduce cast and reducing the accumulation of tolerance to improve accuracy. SOLUTION: Photorceptor 10 is constituted by providing the flange 21 and 22 at both ends of a cylindrical part 20, and rotary shaft 24 is penetrated through the central holes of both flanges to rotatably support the photoreceptor on the rotary shaft. In a through-hole 24b provided one end of rotary shaft 24, the photoreceptor is installed movably in an axial direction on the rotary shaft through a rotation transferring member 26 while integrally rotating. A knob member 28 is screwed in the rotary shaft. The rotation transferring member 26 is pressed by the know member and is integrally engaged with the flange 21, thus transferring the rotation of rotary shaft to the photoreceptor 10 through the rotation transferring member 26. |
