Abstract
An image forming apparatus reduces superimposing misalignment due to skew difference and registration difference and superimposing misalignment of visible image due to periodic position error generated on a plurality of latent image carriers respectively by correcting image information. A controller of the image forming apparatus has a deviation amount storing unit store data of magnification error in the sub-scanning direction e, executes rotation posture determining process that sets writing rotation posture as rotation angle posture at the time of starting writing latent image on photoconductors for Y, M, C, and K respectively, and has an image data correcting unit correct the image information based on the determined writing rotation posture and various error data (including magnification error in the sub-scanning direction e).
