Abstract:
A developer apparatus equipped with at least one transport path wherein a plurality of electrodes are arranged in at least one row to be mutually separated by at least one prescribed spacing and with at least one developer material supply means arranged at front side of said at least one transport path, said developer material being supplied from said at least one of the developer material supply means to the front side, at least one polyphase alternating current voltage being applied to said plurality of electrodes, at least one traveling-wave electric field being formed and causing at least a portion of the developer material to be transported along the front to an image carrier, and the image carrier causing a latent electrostatic image to be developed, said developer apparatus having a rear electrode arranged at a back side of said at least one transport path opposite said at least one developer material supply means, and a developer-material-supplying electric field being formed between the rear electrode and said at least one developer material supply means.
