Abstract
An image adjustment method for an image forming apparatus in which an adjustment image is formed by transferring a plurality of reference images formed by a color component to be the reference among a plurality of color components and a plurality of images to be adjusted, which are formed by other color component to be adjusted, onto a transfer medium so that the images to be adjusted are superposed on the reference images, the density of the formed adjustment image is detected, and an image forming position of the other color component to be adjusted is adjusted based on the detected density of the adjustment image. The density of the surface of the transfer medium is detected, and the position of forming the image to be adjusted is adjusted, based on the detected density of the surface of the transfer medium and the detected density of the adjustment image.
