Title: Temperature control method for fixing device
Inventor: UNEME KAZUHIKO
IPC: G03G15/20
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To perform temperature control so that the temperature of a fixing roller may be within a fixing temperature range by lowering the supply quantity of heat to the fixing roller from a heating means when a temperature detection means detects that the temperature of a paper non-passing area is equal to or above a specified temperature. SOLUTION: When the power source of the fixing device is turned on, a heating element 2 is driven by a driving part 14 and the temperature of the fixing roller attains controlled temperature T0. Then, a control part 13 performs the temperature control based on a detection signal from a temperature sensor 11 so as to hold the temperature T0. When recording paper of minimum size is made to consecutively pass, the temperature of the fixing roller is lowered because the recording paper absorbs heat at a point (s) in a paper passing area (w). Thereafter, the temperature control is performed according to the detected temperature at the point (s) in the area (w), and the temperature is restored to the temperature T0. Meanwhile, at a point (t) in the paper non-passing area (y), the temperature gradually rises because the recording paper does not absorb the heat.  When the temperature at the point (t) attains the specified temperature, the temperature T0 is set to the lower one T0'. Thus, the temperature is controlled at T0' lower than the temperature T0 till then.
