Abstract

PURPOSE:To set waiting time irrespective of the variance of a temperature detecting element by detecting a temperature of a fixing device after a prescribed time, at the time of shifting to a pre-heating state and holding its temperature. CONSTITUTION:When a which is ready to copy state becomes a pre-heating state, a timer 14 operates and counts a prescribed time Wp which has been set in advance, a heat fixing temperature at the time when its prescribed time Wp has elapsed is detected by a detecting means, and its detected temperature Tp is kept constant by a holding means. When preheating is released, the temperature rises and returns to a prescribed temperature Tc and the device becomes a which is ready to copy state, and waiting time Wg at this time is proportional to the previous prescribed time Wp, and becomes constant. In such a way, the time ranging from the preheating time to the copy time can be made constant irrespective of characteristics of a thermistor 8.
