ABSTRACT:
A liquid developing material replenishment system wherein an apparatus for developing an electrostatic latent image with a liquid developing material includes a liquid developing reservoir for providing a supply of operative liquid developing material to the developing apparatus, and a liquid developing material supply is coupled to the liquid developing material reservoir for providing a supply of liquid developing concentrate to the liquid developing material reservoir for replenishing the supply of operative liquid developing material in the liquid developing reservoir. A predetermined amount of operative liquid developing material is periodically and/or systematically discharged from the liquid developing material reservoir to remove contaminated liquid developing material from the reservoir. In addition, a predetermined amount of liquid developing material concentrate is systematically dispensed from the liquid developing material supply to the liquid developing material reservoir so as to extend the useful life of the operative liquid developing material therein.
