ABSTRACT:
A developing device includes a developing sleeve driven to rotate to transport a film of developer riding on its outer peripheral surface, the developing sleeve including an electrically conductive cylinder, a dielectric layer formed on the cylinder and a plurality of fine electrodes provided electrically isolated from each other at least at the outer peripheral surface of the dielectric layer. In one form, each of the fine electrodes is previously coated with an insulating material having the volume resistivity of 10.sup.12 ohms-cm or more to a thickness of 0.5 microns to 0.5 mm. An intermediate dielectric layer may be provided between the cylinder and the first dielectric layer. Further, an electrically conductive layer may be provided as sandwiched between the two dielectric layers. Moreover, the outermost surface of the sleeve may be appropriately roughened in view of the average diameter of toner particles used.
