ABSTRACT:
A method for preparing an elastic roller having a layer of elastic material disposed about and integrally molded to a shaft-shaped core metal member, includes the steps of disposing a cylindrical molding device for holding the elastic material, coating the core metal member with an adhesive, and mounting first and second lid members at opposite ends of the molding device. Each lid member holds a respective end of the core metal member so that the core metal member is disposed concentrically within said molding device. A sealing rubber is disposed between each lid member and the core metal member to prevent elastic material from entering a bearing portion of the core metal member, and the elastic material is injected into the molding device. The elastic material is cured, and the lid members are removed such that an extending portion of each lid member removes burrs formed at peripheral end portions of the roller.
