ABSTRACT:
A thermal fixing device having a heating roller and a pressing member for thermally fixing a toner image held on the front side of the recording sheet. The heating roller is provided to confront the toner image of the recording sheet and the pressing member is provided to confront the back side of the sheet for making pressure contact with said heating roller through the sheet when the recording sheet is transported between the heating roller and the pressing member. The heating roller and the pressing member respectively include heat-resistant elastic layers the surface of which have the triboelectricity to the recording sheet. The heat-resistant elastic layer of the pressing member has higher triboelectricity to the recording sheet than the heat-resistant elastic layer of the heating roller.
