摘要:
A developing roller which shows an excellent environmental performance and is free from occurrence of toner filming and toner leakage is provided. The developing roller 10 comprises a shaft 1, an elastic layer 2 supported on the outer periphery of the shaft 1, and a single surface layer 3 formed on the outer peripheral surface of the elastic layer 2. The elastic layer 2 comprises a polyurethane foam and the surface layer 3 comprises an aqueous polyurethane resin as a major component and further a water-dispersible silica and/or an aqueous silicone acrylic graft polymer. As the aqueous polyurethane resin, a UV curing resin may be preferably used.
