A developing roller for an electrophotographic image forming device and a method for manufacturing the same, the developing roller may include a central shaft and a roller body, the roller body may be made of a rubber-based elastic material, and the roller body may include a pigment having an opposite polarity to a toner used in the electrophotographic image forming device. The developing roller does not cause degradation of a frictional charging capability of the toner, and thus prevents contamination in a non-image zone of the developing roller.
