<p>The present invention provides a sheet conveying roller which requires a smaller number of ingredients than a prior art sheet conveying roller, has an excellent weather resistance, is less liable to suffer from reduction in friction coefficient attributable to accumulation of paper dust and sheet conveying failure attributable to the reduction in friction coefficient, and ensures proper sheet conveyance for a longer period of time. The invention further provides a rubber composition for the sheet conveying roller. The rubber composition comprises an ethylene-propylene-diene rubber and an epoxylated natural rubber as a rubber component. In the rubber composition, the epoxylated natural rubber is present in a proportion of 10 mass % to 90 mass % based on the overall amount of the rubber component including the two rubbers. The sheet conveying roller includes a roller body formed from the rubber composition.</p> |
