PROBLEM TO BE SOLVED: To solve the following problem: when a plurality of electrostatic latent image patterns, which are formed as correction electrostatic latent images, are formed with a predetermined width and intervals, sufficient contrast may not be generated in a detection result based on the presence of the electrostatic latent image pattern. ! SOLUTION: A control means controls forming means to form a second electrostatic latent image including a plurality of electrostatic latent image patterns for adjusting a width of a first electrostatic latent image, while changing a width of the second electrostatic latent image in a photoreceptor rotation direction, to control a width of the first electrostatic latent image in the photoreceptor rotation direction, on the basis of the second electrostatic latent image detected by detection means. !
