PROBLEM TO BE SOLVED: To provide a method capable of manufacturing a conductive foamed roller having good surface roughness and low in contamination properties at a low cost. SOLUTION: In a cylindrical mold 10 having lid members 11, which hold a core metal on the same axis as the inner peripheral surface of a mold, provided to both ends thereof, a raw material composition 13, which is prepared by compounding a foaming agent and various additives with a polymer raw material and kneading the resulting compound, is arranged in the mold 10 along with the core metal to be vulcanized and foamed to manufacture the conductive foamed roller. In this manufacturing method, the inner surface of the mold or the surface of the unvulcanized and non-foamed raw material composition is coated with oil. |
