Abstract

PURPOSE:To shorten the warm-up time and at the same time to save the electric power consumption, by using a 2-step bounce type power supply switch to perform the preheating and the copying at the 1st and 2nd steps respectively and accordingly obtaining a preheating state especially. CONSTITUTION:A contact 1a closes when a power supply switch 1 is turned on by a step, and a temperature control circuit 3 is driven via a low voltage stabilizing power supply 2. Then a heater 5 is heated through a relay element 4 and controlled by the 1st prescribed temperature. At the same time, a preheating pilot lamp 15 is lighted. When the switch 1 is switched to the 2nd step, a contact 1b closes to turn on a low voltage stabilizing power supply 7. As a result, a copy control circuit 8 is driven. The contact at the 2nd step of the switch 1 is held at the contact of a relay, and the circuit 8 is controlled so that a fixing device is set at the 2nd prescribed temperature. At the 2nd prescribed temperature, the copy ready state is displayed.
