PROBLEM TO BE SOLVED: To provide a fixing member which can apply sufficient pressing force to toner particles present on the protrusions of a paper surface, while also maintaining good conformability to the recesses of the paper surface which is an advantage of a surface layer constituted of a soft rubber layer. SOLUTION: The fixing member has the surface layer to come in contact with toner. The surface layer has a sea-island structure in which fluororubber constitutes a sea phase and a silicone compound having a crosslinked structure constitutes an island phase. In a stress-strain curve of the surface layer, the tangential elastic modulus which is the slope of the curve, increases as the strain increases, in a strain range of 0.25-0.8.
