摘要： Disclosed is a toner image fixing device that is capable of changeably setting sheet separating portions in contact with or apart from the cylindrical surfaces of corresponding fixing rollers in accord with the resiliency of recording material to surely prevent a recording material from wrapping round the fixing rollers and being jammed between the rollers and capable of minimizing the frequency of contacting the separating portions with the fixing roller surfaces to obtain an increased quality of a toner image fixed on the recording material and elongate the service life of the fixing rollers.

摘要： Since the paper entry guide is disposed below and in close proximity to a fixing belt, the leading edge of recording paper can become wavy or curled when operated in a high temperature, high humidity environment or when printing on the reverse side of the paper in double-sided print mode, and this has lead to the problem that the leading edge of the recording paper after transfer is not properly inserted in the narrow spacing between the paper entry guide and the fixing belt, resulting in a recording paper jam. A fixing device comprises a fixing belt stretched around a heating roller with a heat source contained therein and a fixing roller, a pressing roller for pressing the fixing roller from below via the fixing belt, and a paper entry guide disposed below and in close proximity to the fixing belt and upstream of a nipping portion composed of the fixing belt and the pressing roller. The paper entry guide is pivotably supported on a fulcrum. A solenoid is provided at the upstream side of the paper entry guide, and a return spring is disposed above the paper entry guide. The solenoid, when in the ON state, pulls a plunger to its lowermost position against the spring force of the return spring, and thereby rotates the paper entry guide in the clockwise direction about the fulcrum to maintain spacing with respect to the fixing belt.

摘要翻译： 由于进纸导板设置在定影带的下方并且靠近定影带，所以当在高温，高湿度环境中操作时或当在双面纸张的背面打印时，记录纸的前缘可能变得波浪或卷曲 这导致如下问题：转印后的记录纸的前缘未被正确地插入纸入口引导件和定影带之间的窄间距中，导致记录纸卡纸。 一种定影装置包括：一个在其上容纳热源的加热辊周围拉伸的定影带和一个定影辊，一个用于经由定影带从下方按压定影辊的加压辊，以及布置在下方并且靠近 定影带和由定影带和加压辊构成的夹持部分的上游。 纸张进入指南可枢转地支撑在支点上。 在进纸引导件的上游侧设置有螺线管，在纸入口引导件的上方设有复位弹簧。 螺线管处于接通状态时，抵抗复位弹簧的弹簧力将柱塞拉至其最低位置，从而使进纸引导件沿支点的顺时针方向旋转，以保持相对于定影带的间隔。

摘要： In one embodiment, a fixing apparatus is configured of a pressing portion for causing the pressure roller to enter a pressure applied state by applying bias, a switching portion for causing the pressing portion in the pressure applied state to enter a pressure released state by causing a cam to rotate forward, a pressure state detection portion for detecting the pressure released state, and a control portion for, when shifting from the pressure applied state to the pressure released state, turning forward the cam of the switching portion in the pressure applied state and stopping the cam after the pressure state detection portion detects the pressure released state. If the cam is turned forward with respect to the switching portion for a certain time period, but the pressure state detection portion does not detect the pressure released state, the control portion performs forward rotational direction retry control.

摘要： A fixing control section of a fixing apparatus according to the present invention includes an end section priority temperature control mode. In the end section priority temperature control mode, the fixing control section temporarily turns off a main heater heating a center section of a fixing roller among a plurarity of heaters disposed inside the fixing roller in a case where a surface temperature of the end section of the fixing roller has reached a preset upper-limit fixing temperature, even if the surface temperature of the center section of the fixing roller is lower than a preset fixing temperature. As a result, destruction of the fixing roller can be prevented by a simple arrangement in the fixing apparatus which includes a plurarity of the heaters disposed inside the fixing roller.

摘要： In a fixing apparatus of the present invention, an end section fixing control temperature changing section selects an end section fixing control temperature in accordance with the number of paper sheets that have been processed in one continuous printing process. A sub-heater on/off determining section turns on or off a sub-heater in accordance with a temperature detected by an end section temperature sensor and the end section fixing control temperature selected by the end section fixing control temperature changing section. This prevents the occurrence of fixing failure even in continuous printing with respect to large-size paper sheets in an arrangement in which a temperature sensor is disposed outside a maximum-size sheet passing region at an end section of a fixing roller and controls energization of a heater which is disposed corresponding to the end section of the fixing roller in accordance with a temperature detected by the temperature sensor.

摘要： In a fixing device including (i) an external heat belt which abuts against a surface of a fixing roller so as to heat the fixing roller and (ii) a cleaning member which abuts against the external heat belt, a fixing temperature, which is a surface temperature of the fixing roller during a fixing process, is set per group into which recording media to be subjected to the fixing process are divided according to their widths in a direction of a rotary axis of the fixing roller, in such a way that the fixing temperature is set to a lower temperature for a group of narrower widths. This makes it possible to prevent a reduction in releasability of the fixing roller caused by a material, which is scraped off from the external heat belt by the cleaning member and then adhered to the fixing roller, thereby preventing the high-temperature offset.
