Heat fixing method and use of a heat fixable toner

摘要

A heat fixing method comprising heat-fixing a toner image formed on a recording medium, to said recording medium by means of a heater element stationarily supported and a pressure member that is opposed to and in pressure contact with said heater element and brings said recording medium into close contact with said heater element through a film interposed between them; and peeling the film from the toner image after the heat-fixing of the toner image, said toner comprises a binder resin and a release agent; said binder resin comprising a polyester resin and said release agent comprising a graft-modified polyolefin, and the surface temperature T3 of said film at the time of being peeled from the fixed toner image is higher than the temperature of the endothermic peak TD of said toner.
