An image forming device capable of controlling a scanning unit and a method to control the scanning unit, the image forming device including a rate error calculator (255) to calculate a rate error from a difference between a practical rotation rate and a target rate of a motor (220) that drives the scanning unit, a position error calculator (256) to calculate a position error from a difference between a current position and a target position of the motor (220), and a rate/position controller (257) to output a control pulse to control a rate and a position of the motor (220) by applying the rate error and the position error. |
