Abstract
A developer, for an electrophotographic image forming system, includes a developer container for storing developing solution, a developing roller which is partially soaked in the developing solution stored in the developer container and installed to rotate in an opposite direction of a photosensitive medium, a cleaning roller, which is soaked in the developing solution, is installed to rotate opposite to the developing roller and removes the developing solution remaining on the surface of the developing roller, and a developing solution agitator, which agitates the developing solution, and thereby keeps the developing solution in uniform concentration. The efficiency of circulation of the developing solution can be increased by upward and downward circulating the developing solution with high concentration stored in the developer container, and the developing solution can be kept in uniform concentration by preventing the developing solution with high concentration from being deposited at the bottom of the developer container.
