Zusammenfassung:	To provide a rubber composition that enables the preparation of a sheet conveyance roller with a superior coefficient of friction.SOLUTION: A rubber composition for sheet conveyance rollers comprises base rubber and petroleum resin. The base rubber comprises an ethylene-α olefin copolymer. Preferably, the rubber composition for sheet conveyance rollers should be prepared by mixing base rubber comprising an ethylene-α olefin copolymer with petroleum resin at a temperature higher than or equal to a softening point of the petroleum resin.SELECTED DRAWING: None 【課題】摩擦係数が優れたシート搬送ローラを作製できるゴム組成物を提供する。【解決手段】シート搬送ローラ用ゴム組成物は、基材ゴムと石油樹脂とを含有し、前記基材ゴムが、エチレン－αオレフィン共重合体を含有することを特徴とする。前記シート搬送ローラ用ゴム組成物は、エチレン－αオレフィン共重合体を含有する基材ゴムと、石油樹脂とを、石油樹脂の軟化点以上の温度で混錬することで得られたものが好ましい。【選択図】なし
