ABSTRACT:
The method of feeding a developer according to the present invention is characterized by controlling the quantity of the developer fed to a developing zone, by the use of a member having on its surface an electret dielectric layer, which is used as an ear cutter. According to the present invention, the quantity of the developer being carried is controlled by the action of an electrostatic force exerted from the electret dielectric layer. Hence it becomes possible to effectively eliminate the density unevenness, charge unevenness of the developer and to obtain a stable image.
