摘要： In continuous printing operation which repeatedly sets a state in which when a preceding printing material passes through the nip area of a thermal fixing unit, a succeeding printing material has been supplied to an image forming unit and image forming operation has been started, a first temperature indicating an ambient temperature near the thermal fixing unit is measured at an early time point in the continuous printing operation. A second temperature indicating the temperature of the printing material which has passed through the press contact nip portion at a predetermined period of time during the continuous printing operation is measured. The amount of heat to be supplied to the succeeding printing material is controlled on the basis of the measured first and second temperatures.

摘要： An image forming apparatus is provided with an image heating apparatus for holding and conveying a recording material bearing an image in a nip between a heating member and a pressurizing member to heat the image on the recording material. The image forming apparatus has a bias applying portion for applying a bias to at least one of the heating member and the pressurizing member and a bias setting portion for setting an amount of the applied bias. In the case that a recording material(s) having a first width is fed and thereafter a recording material is to be fed, the bias setting portion sets the amount of the applied bias based on the number of the recording material(s) having the first width that have been fed and the time from the feeding of the recording material(s) having the first width to the feeding of the recording material having the second width.

摘要： In an image-forming apparatus, a temperature sensor is situated in the position where the sensor is insusceptible to steam. The position is, for example, a portion, of a discharge-sensor lever, where a printing material abuts on the discharge-sensor lever. Accordingly, the temperature sensor becomes insusceptible to steam, whereby the image-forming apparatus can more appropriately control the fixing temperature than conventional image-forming apparatuses. In other words, the image-forming apparatus can more reduce the incidence rate of defects, such as increase, due to excess heating, in the amount of hot-offsets and curls, deterioration of loading capacity, and defective fixing due to scarcity of the amount of heat, than the conventional image-forming apparatuses. Moreover, by determining a threshold temperature every time when a printing material passes through a heat-fixing unit, a problem can be alleviated, in which, at the beginning of a series of paper passage, the amount of fluctuation in detected temperature becomes significantly large.
摘要翻译：在图像形成装置中，温度传感器位于传感器不易于蒸汽的位置。该位置例如是放电传感器杆的一部分，其中打印材料抵靠放电传感器杆。因此，温度传感器对蒸汽不敏感，由此成像装置可以比常规图像形成装置更适当地控制定影温度。换句话说，图像形成装置可以进一步降低由于多余的加热而导致的热偏移和卷曲量的增加，负载能力的劣化以及由于稀缺而导致的固定不良等缺陷的发生率热量比常规图像形成装置高。此外，通过在打印材料通过热定影单元时每当确定阈值温度时，可以减轻问题，其中在一系列纸通过开始时，检测温度的波动量变得显着地大。
