Abstract
PURPOSE: To maintain image densities always constant and announce more than a fixed level of degradation of developing solution by controlling the elements which change image densities according to the degrees of degradation of the developing solution.
CONSTITUTION: Developing solution resistance is measured by the liquid resistance measuring electrode 7 provided within a developing vessel 4. According to this measured value, the electric field to be applied to toner, i.e., the bias voltage to be applied to a developing electrode 4a is changed. It is equally well to output the luminance modulating signal of a cathode ray tube 3 and control the emission luminance thereof or control the voltage of a charger 2.
