ABSTRACT:
In an image forming apparatus, a latent image on a photosensitive body is developed by a developing device and is transferred onto a sheet of paper and remaining toner on the photosensitive body is removed therefrom by a cleaner. The image forming apparatus has a used toner storing portion for collecting the removed remaining toner thereinto and integral with the developing container; a conveyor for conveying the removed remaining toner to the used toner storing portion; and a driving force transmitting device for connecting the conveyor to a rotary shaft of an agitator disposed in the developing device so as to transmit driving force therebetween. When the developing device is replaced by a new one, the used toner storing portion integral with this developing device is also replaced by a new one. The conveyor may have an auger and the driving force transmitting device may have pulleys for the agitator and the auger.
