Abstract
A transfer device has primary transfer rollers supported so as to be upwardly and downwardly movable within a path of movement and opposed to respective of photosensitive drums across a portion of an intermediate transfer belt. There are also provided a slide member for full-color image formation and a slide member for monochromatic image formation, which are capable of reciprocation in a horizontal direction. The transfer device includes roller lifting means each L-shaped and each having one end supporting an associated one of the transfer rollers for rotation and another end engaging an associated one of the slide members, and first and second coaxial rotating cams. The transfer device is capable of switching between three paths of movement of the intermediate transfer belt selectively by the first and second rotating cams rotating together.
