Abstract
A sensor measures the toner applying capability of a toning station. It includes a transparent conductive rotatable member which is rotated through a developer applying zone and a sensing position remote from the developer applying zone. Toner is applied by developer in the station to the exterior surface of the rotatable member as controlled by a bias applied to the rotatable member. The applied toner is sensed by a transmission densitometer at the sensing position. The output can be used to control toner concentration, an original charge on an image member or a development bias applied to the toner station.
