摘要： By blending acicular conductive titanium oxide and an antistatic agent having a metal ion-containing moiety in an organopolysiloxane having at least two aliphatic unsaturated groups, there is obtained a silicone rubber composition which is curable with an organic peroxide and/or an organohydrogenpolysiloxane/platinum group catalyst. The composition cures into silicone rubber having a stabilized resistivity in the semiconductive region, especially in the range of 1×103 to 1×1012 &OHgr;-cm, even under high voltages. The composition is thus suitable as a semiconductive roll material for use as charging rolls, transfer rolls and developing rolls.
