Abstract: Provided are a roller capable of suppressing the generation of cutting waste from the cut surface of a foam layer at the end of the roller in the axial direction thereof, a method of manufacturing especially a conductive roller, and an image forming device using the roller. The roller is provided with a shaft 1, and a foam layer 2 and at least one film layer 3, sequentially provided on the outer periphery of the shaft. The foam layer and film layer are cut at both ends of the roller in the axial direction thereof, and a filler layer 4 for covering at least the foam layer is provided on the cut surface of the foam layer and film layer.
