Abstract
A fusing belt type heat fusing device has a rotating fusing roller, a driven heating roller, an endless fusing belt wrapped and stretched around the two rollers, a pressure roller that applies pressure to the fusing roller through the fusing belt, and a separation agent application and tension transmission element that applies an offset suppression separation agent to the fusing belt in addition to transmitting tension to the fusing belt. The separation agent application and tension transmission element is installed so as to make contact with the fusing belt at an upstream side of the heating roller in the rotation direction of the fusing belt between the fusing roller and the heating roller and at a position closer to the heating roller than a center position between the fusing roller and the heating roller.
