Abstract: PROBLEM TO BE SOLVED: To prevent the color slurring of respective colors in a multicolor image forming device with simple constitution at low cost. SOLUTION: A Y(yellow) motor 40a is started, an interval between pulses outputted from a speed information detecting means (magnetic pattern 45 and MR sensor 41) is measured by a timer unit and the rotating speed information of the motor 40a is arithmetically calculated.

Next, an M(magenta) motor 40b is driven and the difference on the periphery of the rotating body between the cycle of the rotating speed fluctuation per one rotation of the rotating body and that in the case of performing the ideal rotating motion is detected as the irregular rotation information.  Succeedingly, the relative difference of irregular rotation between the motors 40a and 40b is compared. Whether the relative difference is equal to or under a fixed value is judged. When it is equal to or above a certain fixed value and positive, the motor 40b is accelerated for a fixed time, and when it is negative, the motor 40b is decelerated for the fixed time so as to make the relative difference of the irregular rotation of the motors 40a and 40b equal to or under the fixed value.
