Abstract:
An apparatus includes an image formation unit including a photosensitive drum and a motor for driving the image formation unit. The apparatus acquires a frequency generator signal, which is phase information output from the motor as the motor rotates. In addition, the apparatus corrects unevenness of the density that may occur due to the rotation of the motor according to the acquired phase information.
