PROBLEM TO BE SOLVED: To provide an addition-curable rubber composition suitable for manufacturing a rubber for a roll that is free of the tackiness of the rubber surface and oil bleeding and used for electrophotographic image forming apparatuses and the like. SOLUTION: The addition-curable rubber composition for the roll contains (A) a polyoxyalkylene having at least two alkenyl groups in the molecule, (B) an organopolysiloxane having at least two alkenyl groups and containing 10-50 mol% of phenyl groups bonded to silicon atoms based on the total organic groups bonded to the silicon atoms, (C) an organohydrogenpolysiloxane having in the molecule at least two hydrogen atoms bonded to silicon atoms, (D) a platinum catalyst, and (E) an ion conductivity imparting agent.
