Claims

[Claims for Utility Model Registration] 1. A hollow cylindrical image carrier body that can be deformed in the radial direction within an elastic limit; Rotation of an image forming apparatus as an image carrier comprising a supporting member surrounding and supporting the outer circumferential portion of both ends thereof and having a dielectric material attached to the inner circumferential portion for transmitting driving force to the image carrying body. The body is characterized in that a brush made of a conductive material and for transmitting electric charge to the image carrier body is provided at an inner peripheral portion of the support member or at a position in contact with an inner surface side of the image carrier body. The rotating body of the image forming apparatus. 2. A hollow cylinder that can be deformed in the radial direction within an elastic limit, and a device that surrounds and supports the outer periphery of both ends of the hollow cylinder so as not to prevent the hollow cylinder from deforming inward in the radial direction, and that applies a driving force to the hollow cylinder. A rotating body of an image forming apparatus comprising a support member having a dielectric material affixed to the inner periphery for the purpose of transmitting electric charges, and a brush made of a conductive material for transmitting electric charges to the hollow cylinder. The rotating body is provided at a position in contact with an inner circumferential portion of the supporting member or an inner surface of the hollow cylinder, and the rotating body is one of a charging roller, a transfer roller, a developing aura, a neutralizing roller, and a cleaning roller. A rotating body of an image forming device.
