摘要： A fixing device includes a rotatable, endless fixing belt; a rotatable contact member configured to contact a circumferential surface of the fixing belt to form a nip in association with the fixing belt; and a heating member disposed at an interior surface of the fixing belt, configured to heat the fixing belt. The heating member includes a multiple heat sources arranged along the width of a sheet of recording media in a direction perpendicular to a sheet conveyance direction. A controller changes an area to be heated by each heat source based on image data and corresponding to an unfixed image on the sheet. The fixing belt is heated by the heating member so that the unfixed image on the sheet that has been conveyed to the nip is fixed onto the sheet at least with heat. The heating member is disposed at a portion other than the fixing nip.

The rotatable pressure member is disposed opposite the fuser member. The heater heats the fuser member. The rotary driver imparts torque to at least one of the fuser and pressure members. The fuser member and the pressure member are pressed against each other to form a fixing nip therebetween. The thermometer is disposed external to the fixing nip to detect a temperature outside the fixing nip. The controller is operatively connected with the thermometer to control an amount of heat applied to the recording medium through the fixing nip according to the detected temperature, so that the recording medium exhibits a substantially constant post-fixing temperature downstream from the fixing nip.

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.

摘要： An image fixing device that is controllable with a high degree of reliability. The image fixing device is configured with a heat generator for fixing a toner image onto a recording medium that is opposed to an induction heater. Heat is generated in the heat generator through electromagnetic induction. An inverter circuit drives the induction heater. A power controller controls a power value that is output from the inverter circuit, whose power value is calculated by a power-value calculator. A power-value sensor acquires the power value output from the power controller, and a temperature sensor senses a temperature at least at one point of the heat generator. Thus, either the power value sensed by the power-value sensor or a temperature value sensed by the temperature sensor may be used as a reference value to calculate the power value in the power-value calculator.

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。
