Abstract
The apparatus is for heat-fixing a toner image onto a support sheet in which the fixing of toner image is effected through both infrared radiation and direct contact with a heated surface of fixing roller in succession. An endless belt, having a transparency for infrared and trained over a pair of rollers, is disposed within a heat insulating casing, an upper run of the belt defining a path of movement of a toner image bearing support sheet to be fixed. An infrared radiator is disposed beneath the upper run of belt while a reflecting plate is disposed at the opposite side of the belt from the radiator with respect to the path. A fixing roller is disposed downstream of the radiator along the path for completing the fixing.
