Beschreibung
Zusammenfassung:	In a successive development of the images on an electrostatic copy machine, toner concentration within the developer is continuously detected in an optical manner and the supply of the toner to the developer is automatically controlled in accordance with thusly detected time sequential deviation in the toner concentration so as to compensate for the deviation, thereby the toner concentration can be maintained constant even when the copying operation is repeated many times in succession.
