Abstract
Color image forming equipment capable of immediately responding to a sharp change in environment and producing stable images over a long period of time. An information value relating to the amount of toner deposition on a photoconductive element which changes with a change in environment and effects the formation of an image with a reference value which defines a first and a second environment. Variable dynamic range control devices each being optimal for respective one of the first and second environments are selectively used on the basis of the result of the above comparison.
