<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus, capable of reducing the toner amount used for adjusting image forming position and shortening the adjusting time used therefor. <P>SOLUTION: The image forming apparatus is equipped with an image forming means for forming a color image obtained by superimposing a plurality of color component images; and a forming control means for allowing the image forming means to form an image for adjustment for adjusting the forming position of each color component image. The forming control means allows the image forming means, to form a plurality of images for adjustment having a different inclination with respect to the main scanning direction by color. Also, the apparatus is equipped with a means for calculating deviation between a reference position, where the image for adjustment should be formed and a detection position, where the image for adjustment should be detected; and a means for calculating the inclination and section of a regression line, with the reference position and the calculated deviation as variables. The deviation in the main scanning direction and that in the subscanning direction are obtained, based on the inclination and section calculated. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
