PURPOSE:To always keep the bending amount of paper between a resist roller and a photosensitive body constant and to prevent transfer deviation by synchronizing the paper feeding speed of the resist roller with the circumferential speed of the photosensitive body. CONSTITUTION:The resist roller 17 on a driving side is driven by a 1st driving means 26 such as a stepping motor or a servo motor, the photosensitive body 5 is driven by a 2nd driving means 27 for driving a paper feeding roller or a paper ejecting roller, and a fixing roller 19 for heating on the driving side is driven by a 3rd driving means 28 such as the stepping motor or the servo motor. Then, a 1st control means 29 which synchronizes the feeding speed by a pair of resist rollers 16 and 17 with the circumferential speed of the photosensitive body 5 is connected to the 1st driving means 26, and a 2nd control means 30 which decelerates the fixing roller 19 and synchronizes the circumferential speed of the roller 19 with that of the photosensitive body 5 while a paper detecting means 25 outputs a paper detection signal is connected to the 3rd driving means 28. Therefore, the paper feeding speed of the resist rollers 16 and 17 is synchronized with the circumferential speed of the photosensitive body 5. |
