Abstract

PURPOSE: To save wasting of power, by providing means for preheating a fixing unit after lapse of a given time from the time when the copier becomes stand-by, and using a switch for staring copying also for releasing said preheating.
CONSTITUTION: Toner fixing unit 16 is provided with 3 heating lamps HL as heat sources, and heat fixing is carried out with these heat sources. It is necessary to make toner fixing in unit 16 in the optimal temperature range, and it is arranged that copying operation is not started before reaching this range. When power supply is turned on, and copying is finished, and this stand-by state is left without operation of copying, after lapse of 2min, unit 16 is automatically set to preheating. At that time, a 2min timer is reset, heating lamp relay HLR is turned on, a ready lamp is turned off, and preheating PH is turned on, thus permitting heating lamps HL2, HL3 to be cut off by control of circuit WTL.
