A developing device is provided with a developer conveying member in which a plurality of electrodes arranged on a substrate at a predetermined interval are coated with a surface protection layer, the developer conveying member being provided in a developing area that faces an image carrying body whose surface carries an electrostatic latent image, wherein developer is conveyed on the developer conveying member using a traveling-wave electric field that is formed by applying a polyphase voltage to the respective electrodes. The developing device is further provided with a supplying member for supplying the developer onto the developer conveying member, wherein (i) an effective electrode width Le of the respective electrodes in their width direction orthogonal to their arranging direction and (ii) a width Lt of a developer existing area on the supplying member, the width Lt being orthogonal to a direction of supplying the developer, are set so as to satisfy a relation of Lt<Le. This prevents the developer from entering wiring pattern areas outside of the electrodes on the developer conveying member, thereby surely preventing the scattering and the sticking of the developer in the areas.

The invention discloses a method of inhibiting growth of lithium dendrites through organic compound coating. The method comprises the following specific steps of: coating an organic compound on the surface of metal lithium to serve as a protective layer, and directly applying the protective layer to a battery negative electrode. On one hand, the organic compound is rich in Lewis acid functional groups and can interact with anions in an electrolyte, the moving speed of the anions is decreased, and the influence of space charges on the surface of a negative electrode is relieved, so that dendrite growth is inhibited, and on the other hand, lithium ion distribution can be adjusted due to rich lithium-philic elements, the phenomenon that the local lithium ion concentration is too high is reduced, and dendrite growth is inhibited. Therefore, when the coated lithium metal is used in the lithium battery, the coulombic efficiency and the discharge capacity of the battery can be effectively improved, the polarization of the lithium battery is reduced, and the service life of the lithium secondary battery is prolonged.
