Abstract
An intermediate transfer belt having a plurality of layers including a conductive layer, and having a transfer area and a transfer protection area. A CPU sends a control signal to a primary transfer bias generating circuit, and applies a primary transfer bias upon the conductive layer of the intermediate transfer medium through a bias applying member. The CPU changes an output value of the primary transfer bias in accordance with a predetermined bias change condition when a secondary transfer is not ongoing and when a non-image area, in which there is no toner image transferred on the intermediate transfer belt, such as the transfer protection area is passing the primary transfer part.
