Abstract

PURPOSE:To reduce the breakdown of a heating circuit or constitution parts due to short by checking a short between a member to be heated and a heating member or a temperature detecting circuit every fixed time on the basis of an external signal to heat the member to be heated. CONSTITUTION:An internal timing signal circuit outputs a signal for checking short between a heater 2 and the member to be heated, a heater output discriminating circuit 7 disconnects a heater output circuit 3 and connects a short detecting circuit 5, the circuit 5 tests short between the heater 2 and the member 8 to be heated, and the short is generated, sends a heater heating stopping and alarming signal to the circuit 7. The circuit 7 stops the heating of the heater 2 on the basis of the sent signal to prevent current from being leaked into the member 8 to be heated. When the signal from the circuit 5 indiates no short, the heater 2 is heated.
