PROBLEM TO BE SOLVED: To provide an image formation device enabling correction of image distortion in which displacement amount in axial direction of a photoreceptor is different in rotation direction of the photoreceptor.SOLUTION: An image formation device includes a photoreceptor drum which is rotatably provided around a rotational axis, an exposure device in which a plurality of light emitting elements are arrayed in the direction of rotational axis, for exposure by illuminating the plurality of light emitting elements to the photoreceptor drum, and a plurality of dual ports RAM130 for storing image data for making a light emitting element illuminate for each of at least two light emitting element groups arrayed in the rotation axis direction, among the plurality of light emitting elements. By changing a reading cycle for reading image data from the plurality of dual ports RAM130, a light emission interval on the photoreceptor drum is changed for each light emitting element group. |
