Abstract: An image forming apparatus in which a plurality of color component images of different colors, which include a reference color (e.g. black) serving as a reference and adjustment colors (e.g. cyan, magenta and yellow) to be adjusted, are formed on respective photosensitive drums and then transferred to a transfer belt. Respective positions of the color component images transferred to the transfer belt are detected by a CCD. Timing adjustment can be performed so that the difference between the detected position of each of the color component images and a prescribed position is not more than a predetermined value, based on the reference color image as the reference. In this case, the color component images are formed on the corresponding photosensitive drums with the same timing by utilizing a single polygon mirror.
