<P>PROBLEM TO BE SOLVED: To form high-quality color images through highly-accurate adjustment of writing position of each image in a device which forms color images by transferring images formed in a plurality of image-forming units to image carriers respectively. <P>SOLUTION: In a first image-forming station, a photoreceptor drum 21 starts exposure later than a color-based synchronization signal Vsync by a waiting time corresponding to a rotational position at the time when the Vsync is given. In a second image-forming station, the photoreceptor drum 21 starts exposure later than the color-based synchronization signal Vsync by the waiting time corresponding to the rotational position at the time when the Vsync is given. Therefore, regardless of uneven rotation, a top of an image formed in the second image-forming station can be overlapped with a top of an image formed in the first image-forming station. <P>COPYRIGHT: (C)2012,JPO&INPIT |
