Abstract
An image fixing device includes a fixing roller having bearings at each end, a backup roller held in pressure contact with the fixing roller, and a frame receiving the fixing roller and backup roller and having an abnormal temperature rise prevention element. The fixing roller and the backup roller are insertable into the frame in directions perpendicular to the axes of these rollers. The bearing at one end of the fixing roller holds its entire circumference while the other bearing supports only part of the circumference of the fixing roller and the abnormal temperature rise prevention element is set at a predetermined positional relationship to the heating roller as a result of insertion of the heating roller.
