Abstract

PURPOSE:To easily correct the distortion of a copied image, by installing a displacing means which can change the moving direction of the photosensitive body or image forming body or the position of their axis of rotation. CONSTITUTION:A drum-shaped photosensitive body or image forming body 7' is supported by a shaft 13 under a rotation-free condition and one end of the shaft 13 is fitted to the side wall of the main body of this device via a beasing 14 so that the axis of the shaft 13 can change its position both verically and horizontally, and then, the other end of the shaft 13 is supported by a supporting member 11. The supporting member 11 can be removed from and attached to the main body of the device, and, when an eccentric pin 12 fitted to the main body is rotated, the supporting member 11 is moved both vertically and horizontally. As the shaft 11 moves, the shaft and the photosensitive body or image forming body 7' supported by the shaft 13 is also moved both vertically and horizontally with a bearing 14 side acting as a fulcrum. After the photosensitive body or image forming body 7' is moved to a desired position, the supporting member 11 is fixed to the main body by means of a fixing member 16.
