ABSTRACT:
A developing device develops a latent image electrostatically formed on an image carrier in a developing region to produce a corresponding visible image. The developing device includes a rotatable developer carrier for carrying a developer to the developing region and a charging device for forming small closed electric fields in the vicinity of the surface of the developer carrier. The developer is deposited on the surface of the developer carrier by the small closed electric fields. The developer carrier comprises a conductive base and dielectric bodies fixedly buried in recesses formed in the conductive base with each of the dielectric bodies having a predetermined cross-section which extends in a direction of a line normal to the surface of the developer carrier. Also, the developer carrier has a photoconductive surface which is charged by a charging device and selectively illuminated by an illuminating device to deposit a charge on the photoconductive surface which forms a great number of microfields on the photoconductive surface.
