Abstract: <P>PROBLEM TO BE SOLVED: To prevent image quality degradation caused by displacement and contraction/expansion of toner images by correcting the displacement and contraction/expansion of the toner images on an intermediate transfer belt with sufficiently high accuracy even in the case that the operating time of the apparatus is increased or use conditions for the apparatus are altered.  <P>SOLUTION: For a color printer 1, based upon a dot line image and a half-tone image formed in a predetermined calibration pattern, an operator resets a manual correction value for the rotating speed of a photoreceptor and a manual correction value for the leading end of an image formed on a photoreceptor drum 2. Thus, the leading end of the Y toner image of a full color image is made to coincide with the leading ends of Y, M, C and K toner images with sufficiently high accuracy. In addition, the sizes of the Y, M, C and K toner images in their sub-scanning directions can be made equal to one another. Accordingly, displacement and contraction/expansion of the toner images on the intermediate transfer belt 6 can be corrected with sufficiently high accuracy. This effectively prevents image quality degradation caused by displacement and contraction/expansion of the toner images.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
