To provide an elastic roller that prevents peeling-off of an end of a foamed elastic layer from a shaft body and an occurrence of wrinkles on a recording body, and contributes to forming a high-quality image for a long period of time, and a method for manufacturing the elastic roller, and to provide a fixing device for an image forming device and an image forming device capable of forming a high-quality image for a long period of time.

The elastic roller 1 has a foamed elastic layer 3 formed on an outer circumferential surface of a shaft body 2, the Asker C hardness at the two ends 3B and 3C of the foamed elastic layer 3 being greater than the Asker C hardness at its center 3A. The method for manufacturing the elastic roller includes foaming a foamed rubber composition disposed on the outer circumferential surface of the shaft body 2 in a manner to achieve a specific compression rate. The fixing device for an image forming device and the image forming device include the elastic roller 1.
