ABSTRACT:
In a developing device for an electrophotographic image forming apparatus, a toner conveyor roller intervenes between a conveyor roller and a developing region where a photoconductive element is located. A toner is electrically transferred from the conveyor roller to the toner conveyor roller and conveyed by the toner conveyor roller to the developing region. This prevents inversely charged toner particles from being brought to the developing region, thereby insuring high quality development.
