PROBLEM TO BE SOLVED: To obtain an elastomer composition which is most suited in use for a paper feed roller, and the like, has high mechanical strengths, and is most suited in use for applications requiring the affinity with a polar substance, and to provide a paper feed roller which has good affinity with a recording liquid such as a polar water base ink, does not leave the roller marks behind in the printed part on printing and, simultaneously has a high coefficient of friction in addition to excellent durability and abrasion-resistant properties under a high load, and can maintain the high coefficient of friction. SOLUTION: The paper feed roller is molded by using, as the major raw material, the elastomer composition comprising a matrix component composed of a rubber and/or a thermoplastic elastomer, and a compatibilizer compounded therewith, and a polyamide thermoplastic resin having an average particle diameter of smaller than 1μm being finely dispersed in the above elastomer composition and present in a mixed state of small particles having the above average particle diameter of several tens of nanometers and large particles having the above average particle diameter of several hundreds of nanometers.
