摘要： A developing apparatus includes a photosensitive drum positioned in confronting relation to a developing sleeve. A toner accommodating tank is provided for supplying toner to the developing sleeve. The toner accommodating tank is divided into a small chamber and a supplementary chamber which are separated from one another by a partition which permits toner to be supplied from the supplementary chamber to the small chamber but which prevents the return of toner from the small chamber to the supplementary. A movable shutter selectively permits and prevents toner from being supplied from the supplementary chamber to the small chamber in accordance with operation of the apparatus.

摘要： An electrophotographic copying apparatus includes a main body, a developing system, removably mounted on the main body, provided with a developing device having the developing sleeve holding a carrier on the outer surface, and a toner cartridge having a toner supply roller which confronts the developing sleeve. A voltage-adjusting device adjusts the bias voltage to be supplied respectively to the developing sleeve and the toner supply roller depending on a toner color so as to generate a predetermined electric potential between the developing sleeve and the toner supply roller. The voltage adjusting device adjusts the bias voltage difference between the developing sleeve and the toner supply roller according to a saturation charge amount which is different depending on the toner color.
