Abstract:
Disclosed are a conductive roller and a manufacturing method therefor. The surface of an elastic layer in said roller has tiny air pores, and variations in the specific gravity of a coating used to form the elastic layer are minimized. The disclosed conductive roller comprises a shaft (1) and an elastic layer (2) formed on the outer surface of the shaft. The elastic layer (2) comprises a polyurethane foam containing a polyurethane resin and a moisturizing agent. To manufacture the disclosed conductive roller, a blended material containing a polyurethane resin and a moisturizing agent is foamed via mechanical agitation, and a shaft (1) is dipped in the foamed blended material, thereby forming an elastic layer (2) on the outer surface of the shaft (1).
