Summary:PROBLEM TO BE SOLVED: To provide an image forming device which the color slurring of a toner image superposed on a body to be recorded is prevented by perfectly synchronizing the rotation of respective photoreceptor drums by a simple mechanism. SOLUTION: As to this full-color image forming device; the respective photoreceptor drums 4C, 4M, 4Y, and 4K, and a driving motor are connected by a connecting link 2 with the same phase, and also the outer circumferential length π of the respective drums 4C, 4M, 4Y, and 4K is made equal to an interval (d) between them, and the driving signal of the driving motor is corrected based on the detection value of a rotational speed sensor 23 attached to the drum 4C farthest from the driving motor. Therefore, the rotation of the respective photoreceptor drums 4C, 4M, 4Y, and 4K is synchronized, so that phase and amplitude are matched even though rotational irregularity exists. Thus, the positions of the toner images transferred to a recording paper are aligned in respective colors, so that the color slurring does not appear.
