Abstract
An imperfect register correcting method is applied to correcting the incorrect disposition and functions of the components of a multicolor image forming apparatus which forms a multicolor image by sequentially superposing color images formed by a plurality of image forming units thereof, causing imperfect register of the color images formed by the plurality of image forming units. The imperfect register correcting method comprises a first imperfect register correcting cycle in which skews of the image forming units are corrected, and a second imperfect register correcting cycle in which factors of imperfect register other than the skews are corrected. The second imperfect correcting cycle is carried out subsequent to the first imperfect register correcting cycle to obviate the introduction of errors into data for correcting the factors of imperfect register by the correction of the skew of the image forming units.
