摘要：
A fusing unit is comprised of a fusing roller and a pressing roller, having an elastic layer on their outer peripheral surface and a pressing structure for pressing the fusing roller against the pressing roller, and causes a sheet of paper with an unfixed toner image to pass through the nip portion where the fusing roller and pressing roller are put in press-contact with each other so as to fuse the toner image and fix it to the paper. This 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 by the pressing structure.
