Abstract
A Transfer device () includes an intermediate transfer belt (), a plurality of intermediate transfer roller (A-D) and a transfer member moving mechanism (). The transfer member moving mechanism moves the intermediate transfer rollers (A-D) between pressing positions causing the intermediate transfer belt () to be pressed against respective photoreceptor drums (A-D) and separate positions causing the intermediate transfer belt () to be separate from the respective photoreceptor drums (A-D). The transfer member moving mechanism () causes a second pressing position of the intermediate transfer roller for monochrome (A) in monochromatic image forming to be different from a first pressing position of the intermediate transfer roller for monochrome (A) in full-color image forming so that an amount of pressing of the intermediate transfer belt () by the intermediate transfer roller for monochrome (A) becomes greater in monochromatic image forming than in full-color image forming.
