ABSTRACT:
A fusing unit for an image forming apparatus includes a fusing roller and a pressing roller, each having an elastic layer on their outer peripheral surfaces. A pressing structure presses the fusing roller against the pressing roller. When a sheet of paper with an unfixed toner image passes through a nip portion where the fusing roller and pressing roller are in press-contact with each other, the toner image is fused and fixed to the paper. The fusing unit further includes a pressure release lever for regulating the pressing action of the pressing structure when the rollers are put in press-contact with each other.
