PROBLEM TO BE SOLVED: To provide a cylindrical member for electrophotographic device capable of firmly joining an end part supporting body freely attachable and detachably to a cylindrical base without using adhesive agent and being reused. SOLUTION: This cylindrical member composed of the cylindrical base 1 provided with a spiral groove 3 on the inside surface of the end part in a circumferential direction and the end part supporting body 2 provided with a disk-like seat part 2a at a cylindrical shaft part 2b having a projection part 4 which can be screwed in the groove 3 on the outside surface is manufactured. Then, when the supporting body 2 is attached and detached to/from the base 1, the projection part 4 formed on the outside surface of the supporting body 2 is screwed or loosened along the groove 3 formed on the inside surface of the end part of the base body 1 until the seat part 2a of the supporting body 2 abuts on the edge part of the base 1. Thus, the cylindrical member for the electriphotographic device constituted capable of firmly joining the supporting body 2 freely attachably and detachably to the base 1 and being reused is obtained. |
