Estimating the term…
A rubber roller formed by molding an elastomer composition not less than 250 μs nor more than 400 μs in a T2 relaxation time (spin-spin relaxation) of a bound rubber formed between a rubber and/or a thermoplastic elastomer and a reinforcing filler. EPDM can be used as the rubber and/or the thermoplastic elastomer, carbon black as the reinforcing filler, and an organic peroxide as a crosslinking agent. The T2 relaxation time (spin-spin relaxation) of the bound rubber formed between the rubber and/or thermoplastic elastomer and the reinforcing filler is more than a T2 relaxation time of a bound rubber of the rubber and/or thermoplastic elastomer to which the reinforcing filler is not added by not less than 150% nor more than 300%.
An elastomer composition which comprises a rubber and/or a thermoplastic elastomer as a main component thereof and carbon black as a reinforcing filler dispersed in said rubber and/or said thermoplastic elastomer, said carbon black being present in an amount of not less than three nor more than fifteen parts by weight per 100 parts by weight of said rubber and/or thermoplastic elastomer,
