Zusammenfassung:	PURPOSE:To manufacture an elastic roller of good response properties and fixing properties without generation of paper creases by fixing a metal core concentrically in a cylindrical mold and injection a liquid elastic material of low viscosity around said metal core, curing thereon and integrating the metal core periphery and the elastic material. CONSTITUTION:A primer is applied to improve the bonding of a metal core periphery 4 after degreasting A with a liquid elastic material 7. An upper core 2 and a lower core 3 are fitted in and inserted into a cylindrical mold 1 with its inner wall coated with a release agent and assembled with a top force 5 and a bottom force 6. After that, an injection outlet 8 is fitted in a tapered section 9 of the bottom force 6, and a liquid elastic material 7 in the state of low viscosity generated by adding a solvent to silicone rubber is injected between the metal core 4 and the cylindrical mold 1. After that, the cylindrical mold is left in a constant temperature tank to cure silicone rubber. The metal core periphery and the elastic material 7 are integrated. The liquid elastic material 7 contains a platinum catalyst and is cured at the normal temperature.
