Abstract

An apparatus for regulating the developability of a multi-color developing system utilized in a reproducing machine. The regulating apparatus controls image density and maintains color balance. Environmentally induced developabillity changes and toner colorant usage rate variations are adjusted by controlling the concentration of selected toner colorants in the corresponding developer material.
