摘要： PROBLEM TO BE SOLVED: To provide a fixing device capable of appropriately controlling temperature.
SOLUTION: The fixing device has a non-contact thermistor for measuring the temperature of a body to be measured and an infrared sensor (thermopile), and detects the temperatures using both the sensors. When an image forming apparatus is started from the fresh cold time of an image forming apparatus (S101), an amount of correction of the temperature of the non-contact thermistor is determined (S107) from the detected temperature of the thermopile (S103) and the detected temperature (S105) of the non-contact thermistor (S105). After the amount of correction is determined, the temperature of the non-contact thermistor after the correction is used for a soil correction to the thermopile. The non-contact thermistor and the thermopile correct each other, thereby improving accuracy in the detection of the temperatures of the non-contact thermistor and thermopile at the same time.

摘要： PROBLEM TO BE SOLVED: To provide a fixing device designed so as to prevent a heat generating roller from firing even if a coil is supplied with power during the stop of the heat generating roller.
SOLUTION: When the rotation of the heat generating roller 1 is stopped, a magnetic flux intercepting section 5, which intercepts the magnetic flux transmitted to the heat generating roller 1 from a magnetic flux generating body 3, is moved to the position where the heat generating roller 1 does not generate heat by the magnetic flux. On the other hand, when the heat generating roller 1 is rotated, the magnetic flux intercepting section 5 is moved to the position where the heat generating roller 1 generates heat. Therefore, even if a magnetic flux is generated from the magnetic flux generating body 3 as a result of supply of power to the magnetic flux generating body 3 during the stop of the rotation of the heat generating roller 1, the magnetic flux generating body 3 is prevented from generating heat, with the result that the heat generating roller 1 is prevented from smoking or firing.

摘要翻译：要解决的问题：提供一种设计成即使在发热辊停止期间为线圈供电而防止发热辊发火的设计的定影装置。解决方案：当发热辊1的旋转停止时，将从磁通发生体3传递到发热辊1的磁通截取的磁通截流部分5移动到发热辊1不会由磁通量产生热量。另一方面，当发热辊1旋转时，磁通截流部分5移动到发热辊1产生热量的位置。因此，即使由于在发热辊1的旋转停止时向磁通产生体3供给电力，从磁通产生体3产生磁通，所以磁通发生体3是防止发热，从而防止发热辊1吸烟或烧制。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control method for a fixing apparatus preventing destruction of an interface due to rise of temperature on the interface of a pressure roller.
SOLUTION: The control method is for the fixing apparatus 50 provided with a fixing belt 12, a rotating pressure roller 24 which is heated from inside by a pressure side heater 42 and provided with a two layer structure of a metal core 26 and an elastic layer 28, a thermistor 44 detecting the surface temperature of the pressure roller and a control part 72 controlling the supply of power to the pressure side heater 42. The control part 72 usually controls "on" and "off" of the pressure side heater 42 with detected temperature by the thermistor 44 as an input on one hand. On the other hand, the control part carries out control so that supplied power to the pressure side heater 42 is reduced from a usual "on" time when a fixed period has passed with the pressure side heater 42 in the "on" state or when the amount of power during a fixed period exceeds a specified value. Furthermore, while the supplied power is reduced, spacing between paper sheets is made wider than usual during a continuous passing of paper sheets or when the pressure roller 42 is in a rotation stopped state, control is carried out to have it rotate.

In the image forming apparatus, a first allowable range and a second allowable range smaller than the first allowable range which are used as criteria for determining whether or not the quick printing is performed are set, when the next print job is not a print job after jam recovery (S804: N), the first allowable range is selected, and when the next print job is the print job after jam recovery (S804: Y) and the fixing temperature is lower than the present set temperature of the heating member (S807: Y), the second allowable range is selected (S808). When a temperature difference between the fixing temperature and the present set temperature of the heating member is within the selected allowable range (S814: Y), the quick printing is performed (S815), and when the temperature difference is not within the selected allowable range, the image forming operation is started after waiting until the temperature of the heating member reaches the fixing temperature (S816).
