PROBLEM TO BE SOLVED: To provide an image forming device in which cost increase is suppressed and positional deviation of an image caused by the fluctuation in the load of a driving motor is reduced. SOLUTION: A photosensitive body 1 and an intermediate transfer belt 2 are driven by a stepping motor 15. At least two or more kinds of current values are set into a driver 16 which supplies current and these values are made to be switched with an arbitrary timing. Moreover, the driver is made to supply a current having a current value equal to or lower than a stationary current value. Furthermore, when the load is low, a current having a current value lower than the stationary current value is supplied. During a stationary load, a current having a stationary current value is supplied. The switching of the current values is synchronized with the load fluctuation generating timing. |
