PROBLEM TO BE SOLVED: To obtain an excellent image without a smear and irregularity in color, in a type of image forming device provided with plural photoreceptor drums arranged along a carrying belt. SOLUTION: For instance, the circumferential speeds of four photoreceptor drums are detected by photoreceptor drum circumferential speed sensors 12-15, to control photoreceptor drum driving motors 4M-7M, with a CPU 30 and a motor driver 32 and the circumferential speed of the carrying belt is detected by carrying belt circumferential speed sensors 16-19, to control a carrying belt driving motor 34 similarly. Further, the light emission timing of LEDs 8-11 is controlled with an LED driver 36, with the results of the detections of the above-mentioned sensors, to control the formation of toner images formed on the surfaces of the photoreceptor drums. |
