Abstract
PURPOSE: To make optimum heating by setting power supply rate for the current control of a heating unit by a semiconductor control element so that the power supply of said control element of and the stoppage thereof are repeated alternately with the crests of power supply waveform as units.
CONSTITUTION: The signal of a power supply 2 zero voltage detecting circuit 8, a voltage detector 9, a temperature detecting circuit 10 and a humidity detecting circuit 11 are fed to a control system 4 consisting of a lead-on memory 5, a central processor (CPU)6, and an input and output circuit (I/0) 7. Said control circuit 4 operates a triac 3 with a circuit 12 driven by a gate trigger and makes current control of a heating unit 1. The opening and closure of said triac 3 are controlled so as to be made at a predetermined rate for optimum load heating such as duplicator toner heating.
