PROBLEM TO BE SOLVED: To obtain a semi-conductive silicone rubber composition giving rolls for semi-conductive office machines such as a static roll, a copy roll, and a development roll, due to the resistance stability in semi-conductive area of its cured material even under high voltage. SOLUTION: This semi-conductive silicone rubber composition comprises as essential component, (A) 100 pts.wt. organopolysiloxane having at least two aliphatic unsaturated groups as shown by the formula, RnSiO(4-n)/2 (wherein, R is the same or different one-valent hydrocarbon group, and(n) is a positive value 1.98-2.02) (B) about 200 pts.wt. electroconductive titanium oxide whisker, and (C) a curing agent as much as curing (A). |
