Abstract:
An developer bearer conveys developer to a developing station under influence of an electric field created by an electric flux line. The developer bearer includes plural kinds of electrodes that receive different voltages from each other and collectively creates the electric flux line. The plural kinds of electrodes are arranged on different layers in a normal line of the developer bearer. The developer bearer includes an insulation layer that insulates the plural kinds of electrodes.
