DEVELOPEMENT SUPPLYING APPARATUS AND IMAGE FORMING APPARATUS HAVING THE SAME

摘要

PURPOSE: A developer supplying device and an image forming device using the same are provided to extend lifetime. CONSTITUTION: The first developer mixing member(30) mixes developer. The first developer mixing member transfers the mixed developer in the first direction. The second developer mixing member(40) mixes the developer. The second developer mixing member transfers the mixed developer in the second direction. When the filling levels of the first developer chamber and the developer chamber are lower than a preset height, a controller(70) differently controls the filling levels of the first developer chamber and the second developer chamber.
