    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 。

    摘要： An image forming system includes an image forming apparatus including a heating fixing portion and a host computer capable of instructing printing. In the image forming apparatus, throughput can be changed and discriminated in accordance with a printing number. For printing on small size sheets, the system is operable in a normal small size sheet mode and in a high speed small size sheet output mode, in which the printing is effected at a throughput which is higher than that in the normal small size sheet mode and, after completion of the printing, the image forming apparatus rests for a predetermined rest period. The host computer includes a mode selector for selecting a mode from the high speed small size sheet output mode and the normal small size sheet mode, and a controller for transmitting the mode selected by the mode selector to the image forming apparatus.

    摘要： The heat fixing apparatus includes a fixing heater and a pressure roller. The fixing heater has a plurality of resistance-type heat generation layers which are different in heat distribution in the longitudinal direction perpendicular to the direction of conveying a recording material. The recording material P is heated when passed through a fixing nip portion formed between the fixing heater and the pressure roller. The pressurization conditions between the fixing heater and the pressure roller can be changed. The heat fixing apparatus includes a fixing member which adjusts the lengthwise heat distribution of the fixing heater by changing the applied current proportion of the plurality of resistance-type heat generation layers according to the pressurization conditions between the fixing heater and the pressure roller.
