摘要： A fixing device enabling the temperature of a heating element to be uniformly and stably maintained even if the heating element is eccentrically moved or vibrated. An opposed core (233) is so formed that a small diameter opposed core (2332) is fixedly inserted onto the center part of a core shaft (2331) and large diameter opposed cores (2333) are fixedly inserted onto both end parts of the core shaft (2331) so that the cross sectional area thereof at both ends in the lateral direction (both ends in the longitudinal direction) is larger than the cross sectional area thereof at the center part in the lateral direction. A fixing belt (210) is formed of a non-magnetic material and disposed between a core (232) and the opposed core (233). Thus, since a magnetic flux between the core (232) and the opposed core (233) is not almost varied and the fixing belt (210) allows the magnetic flux to pass therethrough and does not affect the flux, even if the fixing belt (210) is rotated and a distance between the core (232) and the fixing belt (210) is varied, the temperature of the fixing belt (210) can be uniformly and stably maintained.

摘要： As a cooling mechanism that cools the entire paper passage area of a heat-producing belt, a rotational drive method of the heat-producing belt is employed and the heat-producing belt is cooled by rotational cooling by being made to idle when paper is not being passed through. An excitation apparatus and the above-described cooling mechanism are controlled so that recording paper is not passed through and the heat-producing belt is cooled while being heated over the heating width when the small-size recording paper is passed through until the temperature detected by a paper non-passage area temperature detecting sensor is at or below a predetermined fixing temperature. This fixing apparatus enables an excessive rise in temperature of a paper non-passage area of the heat-producing belt to be efficiently eliminated, and the temperature distribution of heat-producing belt to be made uniform in a short time.

摘要： PID control performs integral control using an integral value of a deviation between a set temperature and current temperature. In particular, when a proportionality factor Kp is large, a fixing belt reaches a target temperature quickly but overshoot increases. On the other hand, when the proportionality factor Kp is small, the output is reduced gradually, and therefore the fixing belt reaches a target temperature slowly but the overshoot is small. Thus, a heat value control section changes the control value of the PID control according to the temperature (belt temperature) of a fixing belt at the start of heating as detected by a temperature detector. More specifically, a proportionality factor Kp of a calculation expression of the PID calculation is changed according to the belt temperature of the fixing belt. This makes it possible to reduce an overshoot when the temperature of the fixing belt increases.
摘要翻译： PID控制使用设定温度和当前温度之间的偏差的积分值来执行积分控制。特别地，当比例因子Kp较大时，定影带快速达到目标温度但过冲增加。另一方面，当比例因子Kp小时，输出逐渐减小，因此定影带缓慢达到目标温度，但过冲小。因此，热值控制部根据由温度检测器检测到的加热开始时的定影带的温度（带温度）来改变PID控制的控制值。更具体地，PID计算的计算表达式的比例因子Kp根据定影带的带温度而改变。这使得当定影带的温度升高时可以减小过冲。
