<P>PROBLEM TO BE SOLVED: To provide an image forming device of a composition that causes no color deviation, etc. by correcting the alignment of the positions of images when forming a plurality of images in a stacked manner. <P>SOLUTION: A driving device, having a large diameter gear for driving a latent image carrier capable of forming an image of two or more colors, comprises a control part 100 by which a phase deviation of the large diameter gear of the two or more latent image carrier is adjusted with the point of starting up, the point that the fine tuning of the image executed in the vertical scanning direction reaches a predetermined number of times, the point that the number of image forming reaches a predetermined number of times, or the point that the phase deviation of the large diameter gear reaches a predetermined value as a standard, and which is capable of executing the adjustment itself using the period that does not relate to the image forming directly. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
