ABSTRACT:
A developer-supplying system of an image forming apparatus includes a developer-supplying roller supplying a developer onto a developing roller and removing residual developer which is not transferred onto a photosensitive body, but remains on the developing roller after developing, and a residual developer-withdrawing member disposed in a spaced-apart relation with and opposite to the developer-supplying roller to withdraw the residual developer removed from the developing roller by the developer-supplying roller and transferred onto the developer-supplying roller. The developer-supplying system can not only prevent developer-supplying efficiency and residual developer-withdrawal efficiency of the developer-supplying roller from being reduced, but also reduce stress to the developer to prevent the developer from deteriorating.
