Abstract
There is described a method for manufacturing fixing rollers and a roller body holding device utilized for manufacturing fixing rollers. The method includes steps of press-fitting flanges into a roller body, shaped in a hollow cylinder, from each of both end openings of the roller body with putting an elastic material between each of the flanges and the roller body; installing the roller body in a shaping mold so that the roller body is supported by the flanges and the elastic material at a predetermined position in the shaping mold; injecting a melted rubber into a space between the roller body and the shaping mold from an injection opening; and curing the melted rubber injected into the space. The roller body holding device for holding a roller body is shaped in a hollow cylinder and includes a flange, which is press-fitted into the roller body from each of end openings of the roller body; and an elastic material disposed between the flange and the roller body.
