ABSTRACT:
A rubber component containing at least one of diene rubber and ethylene-propylene-diene rubber is dynamically crosslinked. Thereby the rubber component is dispersed in a mixture of a thermoplastic elastomer and a thermoplastic resin. An ethylene oxide-propylene oxide-allyl glycidyl ether and an anion-containing salt having fluoro groups and sulfonyl groups are added to the elastomer composition to obtain a conductive dynamically crosslinked thermoplastic elastomer composition. A mixture of the obtained conductive dynamically crosslinked thermoplastic elastomer composition and a micro-capsule composed of a polymer, having acrylic groups, which forms an outer shell thereof is molded to obtain a conductive roller having Shore A hardness specified in JIS K6253 not more than 40 measured at 23° C.
