Abstract

PURPOSE: To let copying be performed always in the finest condition by controlling various devices in each formed image process based on the outputs of the humidity detector provided on the outside or inside of the copying macnine body.
CONSTITUTION: The output signal from the humidity detector provided of the inside or outside of the copying machine body is applied to the input terminals of comparators 1, 2. Reference voltages a1, a2 are being inputted to the comparator 1. A control circuit 5 applies the outputs of the comparators 1, 2 to a driving control circuit 6. The driving control circuit 6 outputs the driving control signal to a control circuit 7 of heaters for fixing, a temperature retaining heater control circuit 8 for developing part, etc., and a circuit which controls the voltage to be applied to a charger according to the output from the signal control circuit 5.
