PROBLEM TO BE SOLVED: To suppress the generation of rubber powder by reducing abrasion of a sheet feed roller abraded with a pad, etc., in running out of sheet. SOLUTION: This sheet roller includes rubber having EPDM as its main component, hydrogenated styrene thermoplastic elastomer, olefin resin, cross linking activator composed of zinc oxide or zinc carbonate, and resin cross linking agent with halogen added quantity 0.25-1.5 wt.%. The rubber is dynamically crosslinked by resin cross liking agent so as to be dispersed in mixture between the hydrogenated styrene thermoplastic elastomer and olefin resin. |
