<P>PROBLEM TO BE SOLVED: To provide an electroconductive roller keeping a low hardness even under a low temperature environment, having both good moldability and recycling property and obtaining sufficiently low electrical resistance even when only a small amount of salt is added. <P>SOLUTION: The electroconductive roller is formed by a mixture of a dynamically cross-linked thermoplastic elastomer composition made electroconductive by blending ethyleneoxide-propylene oxide-allyl glycidylether copolymer and salt with anion which has fluoro group and sulfonyl group to thermoplastic elastomer and an elastomer composition which is dispersed in the mixture of thermoplastic resin by dynamically linking rubber component containing at least one type of diolefin system rubber or ethylene-propylene-diolefin rubber with a microcapsule with an outer shell made of acrylic group and has a Shore A hardness in JIS K6253 of ≤40 at 23°C. <P>COPYRIGHT: (C)2008,JPO&INPIT |
