On the other hand, when the temperature of the fixing device cap 18 of prediction is below predetermined limit temperature, device is controlled
500 do not make storage device 520 store the temperature of the fixing device 300 measured and the temperature of the fixing device cap 18 of prediction
Data and terminate a series of process.So, limit the temperature of fixing device 300 measured and prediction according to temperature
The temperature of fixing device cap 18 again carry out situation about storing to storage device 520, it is possible to suppression due to repeatedly to
The storage device 520 that storage device 520 stores data and causes deteriorates.
, after reclosing power supply after becoming the state cut off the electricity supply, in order to prognostic chart is as forming apparatus main body 12
The temperature of fixing device cap 18, and use the mensuration temperature storing the fixing device 300 that device 520 is recorded in step S104
The temperature of the fixing device cap 18 of degree and prediction.That is, after reclosing power supply after becoming the state cut off the electricity supply, control
Device 500 uses and stores the temperature of the fixing device 300 that device 520 is stored and store the fixing device that device 520 is stored
The predicted temperature of cap 18 carrys out the temperature of preliminary assay image device cap 18.
As it has been described above, in step slo, for the temperature of preliminary assay image device cap 18, and use that has just predicted to determine
The temperature of image device cap 18 i.e. Tc1.This when switch on power cut off the electricity supply afterwards because temperature sensor 330 nothing
Method measures the temperature of fixing device 300, so there is not the temperature i.e. Tc1 of the fixing device cap 18 just predicted.Therefore, exist
After switching on power, control mensuration temperature and the storage dress of the fixing device 300 that device 500 uses storage device 520 to be stored
The predicted temperature putting the 520 fixing device caps 18 stored carrys out the temperature of preliminary assay image device cap 18.
Now, it is assumed that the ratio reduced relative to ambient temperature at the period fixing device 300 cut off the electricity supply and fixing dress
The temperature putting cap 18 is identical relative to the ratio that ambient temperature reduces, and controls the temperature of device 500 preliminary assay image device cap 18
Degree.That is, when the predicted temperature of fixing device cap 18 being set to Tc, the storage fixing device cap 18 that stored of device 520
Predicted temperature is set to Tc2, is that outer temperature is set to Tair, will connect by the temperature being provided with the environment of image processing system 10
The temperature of the fixing device of the chronometry of power supply is set to Tr, the temperature storing the fixing device that device 520 is stored is set to
During Tr2, control device 500 and carry out the temperature of preliminary assay image device cap 18 according to below formula.
Tc=(Tc2-Tair) × [(Tr-Tair)/(Tr2-Tair)]
Here, the temperature utilizing above formula to predict can be applied certain correction and carry out the temperature of preliminary assay image device cap 18.
That is, when corrected value is set to A, the temperature of preliminary assay image device cap 18 can be carried out according to below formula.
Tc=(Tc2-Tair) × [(Tr-Tair)/(Tr2-Tair)]+A
Here, because the temperature difference of fixing device 300 and ambient temperature is more than fixing device cap 18 and ambient temperature
Temperature difference, so corrected value A allows for the speed temperature more than fixing device cap 18 of the temperature reduction of fixing device 300
The situation of speed reduced and the value determined.
The image processing system 10 of the 1st embodiment described above, the image in step S30 is formed dynamic as shown in Figure 3
In work, storage device 520 is not made to store the predicted temperature etc. of fixing device cap 18, in step after image formation terminates
S100 make storage device 520 store the predicted temperature etc. of fixing device cap 18.Therefore, formed when the image in step S30
During the situation that middle generation is cut off the electricity supply, after storing the predicted temperature of fixing device cap 18 of storage device 520 storage,
Even if the predicted temperature of fixing device cap 18 rises, storage device 520 is not the most made to store the fixing device cap 18 of this rising
