Abstract
A device for developing a latent image on an image carrier in an image forming apparatus is disclosed which includes a developing roller adjacent to the image carrier for transferring a developing agent to the image carrier, a supply roller adjacent to the developing roller for supplying the developing agent to the developing roller and a conductive member contacted with the developing roller. A voltage is applied to the conductive member for generating an electric field on the supply roller to adhere the developing agent onto the surface of the supply roller.
