Abstract

PURPOSE:To perform the printing of distinct two-color image without mixed color by developing an image with 1st toner which mixes in a 2nd developing unit together with 2nd toner on the non-image area of an image carrier. CONSTITUTION:The 1st toner which mixes in the 2nd developing unit 7 from a 1st developing unit 4 develops together with the toner of the 2nd developing unit 7 on the non-image area of a photosensitive body 1. Namely, the image is developed on the area of the photosensitive body 1 between transfer materials, where the photosensitive body 1 is not in contact with the continuously supplied transfer materials and, moreover, the image is developed on the photosensitive body 1 at the time of post-rotating stage of the photosensitive body 1. Then, the 1st toner is removed from the inside of the 2nd developing unit 7 and the mixed color by the 1st toner in a 2nd toner image can be prevented. Thus, the distinct two-color image without the mixed color can be obtained.
