Abstract

Developing apparatus for electrostatic type copying or reproduction machines using dry toner having heating means to heat the developing material whenever temperatures thereof fall below a preset minimum and/or humidity thereof rises above a preset maximum to thereby reduce humidity and absorption of moisture into the developing material. A controller operates the heating means in response to developing material temperatures and/or humidity conditions. Further control means prevents overheating of the developing material. In one embodiment, operation of the heating means is inhibited during operation of the reproduction machine while in another, the heating means is operated on a clock cycle.
