Polymer composition for conductive roller, polymer composition, conductive roller, and conductive belt |
摘要 |
A polymer composition for a conductive roller composed of a rubber component whose main component is an epichlorohydrin rubber containing ethylene oxide at not less than 55 mol % nor more than 95 mol %. Thioureas are added to 100 g of the rubber component as a crosslinking agent at a rate not less than 0.014 mol nor more than 0.080 mol. In a compression set test of a vulcanized rubber described in JIS K6262, a compression set measured at 70° C. for 22-24 hours is less than 15%; and in a volume resistivity value test described in JIS K6911, a volume resistivity value measured at an applied voltage of 1000V is less than 107.5[&OHgr;·cm].
