A silicone rubber composition for thermally conductive silicone-rubber development members which comprisesn(A) 100 parts by mass of an organopolysiloxane having, in the molecule, at least two alkenyl groups each bonded to a silicon atom,n(B) 40-400 parts by mass of a thermally conductive powder that has an average primary-particle diameter of 30 μm or smaller and a thermal conductivity of 10 W/m·K or greater,n(C) 1-50 parts by mass of carbon black, andn(D) a hardener in an amount capable of curing the component (A) andnwhich gives a cured silicone rubber having a thermal conductivity of 0.28 W/m·K or greater. With the silicone rubber composition for thermally conductive silicone-rubber development members, it is possible to provide a thermally conductive silicone-rubber development member (roll, belt, etc.) which comprises a silicone rubber layer formed by curing the silicone rubber composition and which is excellent in terms of image characteristics and has the feature of high thermal conductivity. |
