Fixing member and method of manufacturing the member, fixing device, and electrophotographic image-forming apparatus

Abstract

Provided is a fixing member having a silicone rubber elastic layer blended with a carbon nanotube, the fixing member suppressing peeling at an interface in association with insufficient adhesion between a base member and the silicone rubber elastic layer at the time of the use of the fixing member, and hence securing adhesion durability. The fixing member includes a base member, an elastic layer, and a surface layer, in which: the elastic layer contains a silicone rubber and a carbon nanotube; a ratio E200/E50 of an elastic modulus E200 of the elastic layer at 200° C. to an elastic modulus E50 of the elastic layer at 50° C. is 0.5 or more and less than 1.0; an adhesive strength between the elastic layer and the base member is 3.0 N/cm or more and 20.0 N/cm or less; and the elastic layer undergoes a cohesive failure at the time of a peel test.

Dependencies are inferred from the claim text.
