PROBLEM TO BE SOLVED: To provide a silicone rubber composition providing a silicone rubber which has excellent thermal conductivity, a little permanent compressive strain, and excellent long-term durability at a high temperature and is suitable as a covering material for a fixing roll, in particular a heat roll, and to provide the fixing roll in which a silicone rubber layer comprising the cured composition is formed on the circumferential surface of a metal core. SOLUTION: The composition is characterized by containing: (A) liquid organo-polysiloxane containing an alkenyl group combined with at least two silicon atoms in one molecule; (B) liquid organo hydrogen polysiloxane containing three hydrogen atoms combined with at least a silicon atom in one molecule; (C) one or more kinds selected from siloxane compounds having a specific structure; (D) thermally conductive inorganic fine particles; and (E) an addition reaction catalyst.
