PURPOSE:To prevent deviation and snake motion of a belt, by installing the endlessly running belt which is stretched between two rollers, and regulating members which contact with both roll-in sides of the belt where the belt first contacts with the rollers to regulate the snake motion of the belt. CONSTITUTION:A wide transferring belt 17 having a width which is almost equal to that of phtotosensitive substances 4 is stretched between a drive roller 15 and a guide roller 16, and makes an endless movement in accordance with the rotation of the drive roller 15. Moreover, at the side of the guide roller 16 where the transferring belt 17 first touches the guide roller 16, regulating members, such as cylindrical regulating rollers 24 and 24, which regulate the snake motion of the belt 17 are installed. Therefore, when the transferring belt 17 tends to deviate to either side in the direction of the width of the belt, the belt 17 is push backed to the proper position by the regulating rollers 24 and 24, and thus, the deviation and snake motion of the belt 17 are prevented. |
