  • Patent number: 10452015
    Abstract: When a mechanism enters a first state, an intermediate transfer member separates from a second photosensitive member. When the mechanism enters a second state, the intermediate transfer member contacts the second photosensitive member. When a first monochrome image is formed on a sheet of a first type by using toner of a first color, the mechanism enters the first state. When a second monochrome image is formed on a sheet of a second type by using toner of the first color, the mechanism enters the second state. A rotation speed of the second photosensitive member for forming the second monochrome image on the sheet of the second type is controlled to a predetermined rotation speed. The predetermined rotation speed is slower than a rotation speed of the second photosensitive member for forming the second image.
