Abstract

One of the failure modes of a conductive electrostatographic developer material occurs when the developer material becomes insulating due to toner impaction on the carrier. Developer failure may be prevented by measuring the conductivity of the developer with a current sensor to measure the current flow through the developer. Alternatively, a voltage sensor may be employed to measure the voltage across the developer with a level detector.
