<P>PROBLEM TO BE SOLVED: To inexpensively prevent color deviation by a simple composition in an image forming device of a composition driving a plurality of image carriers by one driving means. <P>SOLUTION: An inter-drum distance of two photoreceptor drums attached with drum gears 33a and 33b is set at an integral multiple of a drum circumferential length. By adjusting meshing of the drum gears 33a and 33b to a driving gear 31 such that a fluctuation width of a driving current of a motor 30 driving the drum gears 33a and 33b becomes maximum, phase shifts due to eccentricity are synchronized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
