摘要： In one embodiment, an operation state, standby state or installation environment of an image forming apparatus is detected or determined, and details of heating control of the surface temperature of rollers of a fixing apparatus are changed in accordance with the detected or determined state or environment. For example, when the operation state is a state in which printing on a last sheet of recording paper in a print job is complete, or when the operation state is a state in which printing on recording paper is interrupted, and, in addition, when the installation environment is a low-temperature and low-humidity environment and the image forming apparatus enters the standby state, heating of the rollers is respectively controlled to prevent unexpected and inappropriate changes in the surface temperature of the rollers.

摘要： A fixing device includes a feeding roller for feeding a belt-shaped cleaning member which has been rolled up, and a winding roller for taking up the cleaning member which has been fed from the feeding roller and cleaned a surface of the fixing roller, the winding roller being provided so as to pressure-contact the feeding roller. The winding roller is rotated by a time control due to a control portion so that a sum of a feed amount of the cleaning member which is fed by the feeding roller at one feeding occasion, and a take-up amount of the cleaning member which is taken up by the winding roller at one take-up occasion, is equal to or more than a double of a length Ln of a nip section.

摘要： In the present applying mechanism, a part of a guide sheet 33 bulges (arches) away from an oil application roller 16, with respect to a vertical line S passing through the center of a pipe 31. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding (bypassing) the oil application roller 16 that has a high temperature. With this, oil flowing on the guide sheet 33 is kept away from the high-temperature oil application roller 16. On this account, it is possible to restrain the degradation of the oil flowing on the guide sheet 33 on account of the heat from the application roller.

摘要： An armored unit includes a side cover and a guide member. When sheet jam operation is carried out, a fixing unit is pulled out with the armored unit, and then is pushed to the rear side. This operation unlocks the lock member provided in the guide member, and a shoulder screw moves in a guide hole. Thus, the fixing unit is moved from the pulled out position toward the rear side and toward the main body of image forming device to be shifted to a receding position. On this account, it is possible to provide an image forming device ensuring sufficient space for removing a jammed sheet by hand with a small opening space.
摘要翻译：铠装单元包括侧盖和引导构件。当进行卡纸操作时，用铠装单元拉出固定单元，然后将其推向后侧。该操作解除了设置在引导构件中的锁定构件，并且肩部螺钉在引导孔中移动。因此，定影单元从拉出位置朝向图像形成装置的主体朝向后侧移动并且朝向图像形成装置的主体移动以转移到后退位置。因此，可以提供一种图像形成装置，确保用小的开放空间用手去除卡住的片材的足够的空间。
