Abstract
A rubber roller formed by molding an elastomer composition not less than 250 μs nor more than 400 μs in a Trelaxation 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 Trelaxation time (spin-spin relaxation) of the bound rubber formed between the rubber and/or thermoplastic elastomer and the reinforcing filler is more than a Trelaxation 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%.
