Abstract
PURPOSE:To exactly predit the timing for becoming a copy available state, by displaying a temperature difference between the temperature of a fixing device and a prescribed temperature value, or the time required for reaching the prescribed temperature value, when the temperature of the fixing device does not reach the prescribed temperature value. CONSTITUTION:A temperature detecting means 12 detects the temperature of a heating roll 9 of a fixing device 8. Subsequently, an arithmetic means 22 compares this detected temperature with a prescribed temperature value, its difference is calculated, and when its difference is larger than a value determined in advance, the time when the temperature of the heating roll 9 reaches the prescribed temperature value is calculated. Subsequently, a display means 25 displays the temperature difference of the detected temperature and the prescribed temperature value, or the calculated time. In such a way, the timing for becoming a copy available state can be predicated exactly.
