Abstract
In a fixing method for fixing a toner image to a transfer medium, heat-and-pressure fixing is carried out using a specific pressure member and a specific toner. The pressure member has a heat-resistant elastic layer having a thermal conductivity of 0.20 W/m·K or below. The toner has, in its DSC endothermic curve, at least a maximum value in the region of temperature of from 105° C. to 150° C., and, in GPC of THF-soluble component of the toner, a main peak in the region of molecular weight of from 2,000 to 25,000, a sub-peak or shoulder in the region of molecular weight of 70,000 or higher, and an Mw/Mn ratio of 8 or higher, containing 20% to 70% of a component belonging to the region of molecular weight of from 1,000 to 10,000.
