Abstract

Embodiments relate to a developing device for use in an image-forming apparatus including a developing roller having a conductive base surface which may be covered with a resin layer containing an ion conductive material and a silicone-modified urethane resin having an ether structure. The resin layer may be a product of a crosslinking reaction of the silicone-modified urethane resin and the ion conductive material in the presence of a crosslinking agent and a crosslinking catalyst.
