In this apparatus, the Currie temperature Tc of the magnetic adjuster material heated by electromagnetic induction is set to 220 degrees C. or below and the fixation setting temperature of a heating member corresponding to the portion where a recording material passes during continuous sheet feed is set lower than a value than the temperature at which the relative magnetic permeability of the magnetic adjuster material begins to decrease.

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： 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.

Toner used for an electrophotographic method using an intermediate transfer member includes additives such as inorganic fine particles, having a particular particle diameter and specific surface area, arid hydrophobic silica having a particular specific surface area and surface treatment, so that the toner can provide images of high quality and high transfer efficiency without generating photoconductor and intermediate transfer member filming.

摘要： The present invention relates to an image forming apparatus that enables the occurrence of print defects due to a first print start time delay to be eliminated without using a temperature sensor that has a small thermal time constant. When the temperature of a fixing belt serving as an image heating body is greater than or equal to a predetermined temperature following the elapse of a fixed time after an image forming operation is started, recording paper is transported to a nip area (fixing area) of a fixing apparatus before the temperature detected by a temperature sensor reaches a predetermined image fixing temperature, and an image forming operation is started immediately.
