Abstract
A fixing belt including a base layer, an elastic layer and a surface layer, wherein the elastic layer has a total thickness of 200 to 3,000 μm, has a thermal conductivity of 0.4 W/(m·K) or more in a total thickness direction thereof, and contains fillers in a content of 40 to 60 vol % with respect to the total volume of the elastic layer. The fillers in a region A of the elastic layer have a practical sphericity SA of 0.75 or more, and a content ratio of the fillers in the region A is 60 vol % or less with respect to the region A. The fillers in a region B have a practical sphericity SB of less than 0.75, and a content ratio of the fillers in the region B is 40 vol % or more with respect to the region B.
