ABSTRACT:
A developer density detecting apparatus in a copying machine including a detector roll assembly rotatably supported adjacent to a developing roll. The detector roll assembly comprises a sleeve and a plurality of magnets attached to the inner peripheral surface of the sleeve. The magnets are arranged to have different polarity alternately and terminates in the same polarity at both peripheral ends. A conductive glass is provided for receiving toners from the detector roll assembly. Mounted on the conductive glass is a photoelectrical detector for detecting developer density from the toners adhered to the conductive glass.
