Abstract: PROBLEM TO BE SOLVED: To provide an air treating system for a developing housing which prevents the toner discharge to a device cavity, and guarantees an adequate copy printing. SOLUTION: This device includes a housing 66 having a toner feeding source; a doner roll 40 provided to the housing 66 in order to transfer a toner to a developing area near the surface; an electrode wire 42 being a means to separate the toner from the doner roll 40, and to form a toner cloud in the developing area; and an air processing system attached to the housing 66, which collects the floating toner particles discharged from the housing 66. And, this air- processing system includes a separator 200 to separate the toner according to its size.
