PROBLEM TO BE SOLVED: To provide a rubber composition capable of forming a paper feeding roller hardly generating reduction of friction factor μ, having appropriate hardness, small in permanent elongation and excellent in abrasion resistance, a paper feeding roller formed by using the rubber composition, and an image forming device incorporating the paper feeding roller.SOLUTION: The rubber composition contains both of high ethylene EPDM and low ethylene EPDM as rubber components and a ratio of the high ethylene EPDM is 30 to 80 mass% in the total amount of the rubber components. A paper feeding roller 1 is made of the rubber composition. The image forming device incorporates the paper feeding roller. |
