<p>PROBLEM TO BE SOLVED: To provide an image forming device, which can move a belt such as a transfer belt, with a simple structure. SOLUTION: A shaft 711 having torque limiters 76A and 76B right below the followers 67A and 67B of a transfer belt unit 60 is pivotally supported in the direction of the width of the unit. The rotating-and-driving force of a fixing roller 83 is transmitted to the shaft 711 via belt pulleys 71 and 72, a V-belt 74, spur gears 75 and 81, and an idle gear 73. The transfer belt unit 60 is brought into press-contact with the periphery surface of a photoreceptor drum by pushup levers 765A and 765B.</p> |
