Abstract

This disclosure relates to a developer flow meter for use in controlling the operation of an automatic development control (ADC). Illustrated in the drawing are an ADC 10 and a flow meter 12. The ADC comprises a pair of parallel plates 14 and 16, the latter of which is adapted to have a voltage applied thereto through a voltage switching circuit schematically represented by reference numeral 18. The plate or electrode 16 comprises a window area in which toner is either deposited on or scavenged from depending on the polarity of the voltage applied to the electrode.
