摘要： A heating apparatus that enables an abnormally high temperature detection section that detects, when a heating element heated by means of electromagnetic induction reaches an abnormally high temperature, this abnormally high temperature, to operate speedily and reliably irrespective of the material and temperature characteristic of the heating element in a low-cost and compact configuration. In this apparatus, thermostat 301 is disposed on the same side as exciting coil 231 with respect to heat generating belt 210 and between winding bundles of a conductor wire of exciting coil 231. This allows coil guide 234 to hold both thermostat 301 and exciting coil 231 and allows these wires and terminals to be concentrated on one location, thus making it possible to reduce the number of parts and assembling man-hours and configure the body of the apparatus in a low-cost and compact configuration. Furthermore, thermostat 301 operates reliably when heat generating belt 210 reaches an abnormally high temperature irrespective of whether the material of heat generating belt 210 is a magnetic member or not and whether the temperature of heat generating belt 210 has exceeded a Curie temperature or not.

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, and therefore when a proportionality factor Kp is large, a fixing belt 230 reaches a target temperature quickly but a subsequent overshoot increases. On the other hand, when the proportionality factor Kp is small, the output is reduced gradually, and therefore the fixing belt 230 reaches a target temperature slowly but the overshoot is small. Thus, a heat value control section 300 changes the control value of the PID control according to the temperature (belt temperature) a fixing belt 230 at the start of heating of detected by a temperature detector 270. 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 230. This makes it possible to reduce an overshoot when the temperature of the fixing belt 230 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进行积分控制，因此当比例因子Kp大时，定影带230快速达到目标温度，但随后的过冲增加。另一方面，当比例因子Kp小时，输出逐渐减小，因此定影带230缓慢地达到目标温度，但过冲较小。因此，热值控制部300根据由温度检测器270检测到的加热开始时的定影带230，根据温度（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230的带温度而改变。这使得当定影带230的温度升高时可以减小过冲。

摘要： An image recording apparatus has a paper feeding system, a process unit for performing an electrophotographic process, a fixing system, an optical system, and a delivery system. The process unit is detachable from a main body through a front cover. The front cover has a container attached to its inner surface. The process unit can be divided into two parts which are separable from each other: a first part including a developer and a toner cartridge, and a second part including a photosensitive drum, a charger, a transferrer, and a cleaner. The paper feeding system is disposed on an upper portion of a main body of the image recording apparatus. The process unit and the fixing system are positioned diagonally below and forward of the paper feeding system such that a paper path connecting the paper feeding system and the fixing system descends forward. The optical system is disposed in a lower portion of the main body in such a manner as to partially underlie the process unit.
