To easily manufacture an elastic roller, at low cost, which has a smooth surface and high dimensional accuracy when the elastic roller comprising a core metal and an elastic body layer disposed on the periphery of the core metal is molded using a tubular metal mold, and is free of defective adhesion between the elastic body layer and a surface coating even when a protective layer is formed on the surface of the elastic body layer.
In the elastic roller comprising a core metal and an elastic body layer disposed on the periphery of the core metal, the elastic body layer contains a substance having a melting point of ≥100°C. The content of the substance having a melting point of ≥100°C in the elastic body layer is made higher on the surface of the elastic body layer than in the interior of the elastic body layer.
