Abstract
An image forming apparatus effectively prevents scattering of a toner image transferred to an intermediate transfer belt. The image forming apparatus has an image carrier,on which a toner image T formed according to image data is held; an intermediate transfer belt,disposed facing the image carrier,and supported on so as to move circularly about plural rollers,with tension applied; a first bias transfer unit,for sequentially transferring a toner image T on image carrier,to intermediate transfer belt,; and a second bias transfer unit,for batch transferring the toner image T on intermediate transfer belt,to a recording medium,; and a potential holding unit,for holding the surface potential of the first contact member,at or above the charge potential of the back of intermediate transfer belt,, and disposed to the contact member,first contacting the intermediate transfer belt,after it passes the first bias transfer unit
