Abstract: Provided is a conductive roller coating composition which can reduce degradation of toner during durable printing when used for a developing roller, and a developing roller and image formation device using the same. In a conductive roller coating composition containing a resin component including a polyol and an isocyanate, and microparticles, a Tg of the microparticles is −13° C. or less. In a developing roller including: a shaft 1; and an elastic layer 2 supported on an outer periphery of the shaft 1, an outer periphery of the elastic layer 2 is coated with the conductive roller coating composition.

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.
