Abstract
In an image forming device, a main controller unit controls the image forming device, a motor controller unit controls individually rotational speeds of a plurality of motors rotating image carriers respectively, and a deviation detection unit detects a deviation of the color image. In the main controller unit, a speed signal transmitting unit transmits a speed signal, indicating a target rotational speed for correcting the deviation, to the motor controller unit. An enabling-signal transmitting unit transmits, to the motor controller unit, a speed-change enabling signal after passing of a predetermined time from a time an imaging reference signal, which is indicative of a start and an end of an image region of each color, indicates an end of a corresponding image region immediately after transmission of the speed signal.
