PROBLEM TO BE SOLVED: To provide a color image forming device for realizing the high image quality and the high speed output of a monochromatic image and the simplification of a fixing device in the color image forming device. SOLUTION: At the time of forming a color image, the toner images of respective colors formed on a photoreceptor belt 10 are successively transferred on a transfer body 16, and transfer material S is guided to a carrying route under the transfer body 16 on an opposite side to the photoreceptor belt 10, and the image is transferred by applying high voltage power supply output having a reverse polarity to toner by a second transfer means 22. At the time of forming the monochromatic image, the transfer material S is guided between the photoreceptor belt 10 and the transfer body 16, and a monochromatic toner image formed on the photoreceptor belt 10 is directly transferred on the transfer material S by applying the high voltage power supply output having the reverse polarity to the toner by a first transfer device 17. |
