Zusammenfassung:	To provide a sheet conveyance roller that can suppress a decrease in coefficients of friction, even when repeatedly conveying sheets with a high content of silicate components such as silica and talc.SOLUTION: A rubber composition for sheet conveyance rollers comprises, as base rubber, (A) an epichlorohydrin-ethylene oxide-allyl glycidyl ether copolymer and (B) a diene rubber. In 100 mass% of the base rubber, the content of the (A) epichlorohydrin-ethylene oxide-allyl glycidyl ether copolymer is 20 mass% or more.SELECTED DRAWING: None 【課題】シリカやタルクなどのシリケート成分を多く含むシートを繰り返し搬送しても、摩擦係数の低下を抑制できるシート搬送ローラを提供する。【解決手段】シート搬送ローラ用ゴム組成物は、基材ゴムとして、（Ａ）エピクロルヒドリン－エチレンオキシド－アリルグリシジルエーテル共重合体と（Ｂ）ジエン系ゴムとを含有し、前記基材ゴム１００質量％中の前記（Ａ）エピクロルヒドリン－エチレンオキシド－アリルグリシジルエーテル共重合体の含有率が２０質量％以上であることを特徴とする。【選択図】なし
