PURPOSE:To provide the developing device which has a sufficient capacity to transport a developer and does not generate a difference in image density and a degradation in image density. CONSTITUTION:This developing device has a developing roller 109 for supplying the developer to an image carrying member, a layer forming means for forming the thin layer of the developer on the surface of this developing roller 109, a supplying roller 111 for supplying the developer to the developing roller 109, a conductive metallic member 121 pressed to the surface of the supplying roller 111 in order to bring the developer supplied from the supplying roller 111 into sliding contact therewith, and a voltage impressing means 20 for impressing a bias voltage to this conductive metallic member 121. The capacity to transport the developer is improved by the effect of the conductive metallic member 121 and the voltage impressing means 20. The difference in the image density and the degradation in the image density are prevented. |
