Abstract:
1. A conductive elastomer composition comprising an ionic-conductive elastomer component, and an anion-containing salt having a fluoro group (F—) and a sulfonyl group (—SO 2 —), said conductive elastomer composition having: a volume charge not more than 10 a compression set not more than 30% when said compression set is measured at a temperature of 70° C. for 24 hours at a compressibility ratio of 25% in accordance with “the permanent set testing methods for rubber, vulcanized or thermoplastic” specified in JIS K6262, and a hardness not more than 75 degrees when said hardness is measured by a durometer of type E specified in JIS K6253, and wherein said conductive elastomer composition is a vulcanized rubber composition comprising: epihalohydrin rubber, as said ionic-conductive elastomer component, which comprises epihalohydrin, ethylene oxide, and allyl glycidyl ether copolymerized at a ratio of 10 to 45 mol %, 55 to 80 mol %, and 0 to 10 mol % respectively; and not less than 0.01 nor more than 20 parts by weight of said anion-containing salt having said fluoro group (F—) and said sulfonyl group (—SO
