Abstract
The present invention relates to a fixing member that can apply sufficient power to press toner particles on a raised portion of a paper surface while also maintaining good conformability to a depressed portion of the paper surface that is an advantage of a surface layer including a soft rubber layer. The fixing member has a surface layer to come into contact with toner, the surface layer has a sea-island structure in which the fluororubber constitutes a sea phase and a silicone compound having a crosslinked structure constitutes an island phase, and in a stress-strain curve of the surface layer, the tangential elastic modulus, the slope of the curve, increases as the strain increases, in the strain range of 0.25 to 0.8.
