1. An image forming device comprising:
an image forming unit forming an image on a printing medium in a predetermined cycle in a direction orthogonal to a conveying direction of the printing medium; a velocity acquisition unit acquiring a conveying velocity of the printing medium at a position where the image is formed by the image forming unit; and a correcting unit correcting the cycle on which the image forming unit forms the image on the printing medium in accordance with the conveying velocity acquired by the velocity acquisition unit, wherein the image forming unit comprises: an exposing unit exposing an image carrier, rotating in a direction parallel to the conveying direction of the printing medium, to light in the predetermined cycle in a direction orthogonal to the conveying direction and with a certain exposure timing; and a transferring unit forming the image on the printing medium by transferring to the printing medium the image based on a latent image formed by exposing the image carrier to light by the exposing unit, wherein the correcting unit corrects the cycle on which the transferring unit forms the image on the printing medium by changing the certain exposure timing only during a certain time period within a time when the transferring unit forms the image on the printing medium, the certain time period being less than an entirety of the time when the transferring unit forms the image on the printing medium.
