Abstract
The present disclosure provides a fixing member that has a substrate, and a single layer of an elastic layer on the substrate, the elastic layer having a thickness of 100 μm or more, and containing a binder and a filler, wherein the elastic layer contains the filler in a content of 30% by volume or more to 60% by volume or less based on the total volume of the elastic layer, and wherein, when a surface of the elastic layer facing to the substrate is defined as a first surface, and a surface of the elastic layer opposed to the first surface is defined as a second surface, an average value of ratios of an element derived from the filler is 0.0 atomic % or more to 6.0 atomic % or less in a region having a thickness of 6 μm, from the first surface toward the second surface.
