Abstract
Provided is a fixing member for a heat fixing apparatus which can further improve utilization efficiency of heat for heat fixing of an unfixed toner. A fixing member having an endless belt shape includes a substrate and an elastic layer on the substrate, wherein the elastic layer includes silicone rubber and a filler dispersed in the silicone rubber, and when a thermal conductivity of the elastic layer in a thickness direction is defined as λnd, a thermal conductivity of the elastic layer in a circumferential direction is defined as λtd, and a thermal conductivity of the elastic layer in a width direction is defined as λmd, λnd is 1.30 W/(m·K) or more, and λnd, λtd, and λmd satisfy a relationship as shown below λnd>λmd>λtd.
