摘要： An image forming apparatus uses a plurality of image forming units having photosensitive drums and that are arranged rotatable in a vertical plane such that the image forming units are shifted sequentially to an image forming position. Each of the image forming units has a rectangular concave portion along its longitudinal direction which contains a handle made of an elastic rectangular-shaped plate. The handle has elongated holes extending in the longitudinal direction at both ends of the handle which engage anchoring members provided at the concave portion. The handle is allowed to be contained within the concave portion by its elastic force and is allowed to be pulled out from the concave portion by a user's finger inserted into an entrance groove provided only at a side opposite to the photosensitive drum with respect to the handle. In addition, the image forming apparatus has a door for allowing the attaching/detaching of the image forming units wherein the door has a protrusion which is capable of contacting the handle.

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： There is provided a fixing apparatus capable of reducing the warm-up time, improving the heating efficiency, and suppressing the temperature increase out of the sheet width by using a magnetic adjuster. 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. Thus, it is possible to obtain a large difference between the heating portion and the non-heating portion, to surely prevent excessive temperature increase of the portion out of the recording material width, to reduce the warm-up time, and improve the heating efficiency.

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。
