Abstract
Provided is a fixing belt which has high thermal conductivity capable of achieving an excellent fixing property that can respond to the recent increase in printing speed, which has a proper degree of elasticity such that color toners are sufficiently enveloped so as to be melted and mixed, and which has excellent mechanical strength and durability. A fixing belt includes a tubular base member, an elastic layer disposed on the outer circumferential side of the base member, and a surface layer disposed on a surface on the outer circumferential side of the elastic layer, the fixing belt being characterized in that the elastic layer is composed of rubber into which a filler primarily composed of silicon carbide powder and a carbon nanotube are compounded, and the formulae 10X+3Y<750, 3X+30Y>170, X>10, and Y>0.1 are satisfied, where X is the percent by volume of the filler and Y is the percent by volume of the carbon nanotube in the elastic layer.
