The developer roll includes a wound roll of media and a layer of resin. The wound roll is formed from a sheet of the media. The layer of resin is applied to the periphery of the wound roll. The layer of resin and the roll of media are selected of materials to obtain a decay rate relating to the electrical response of the layer of resin to the applied voltage differential.
