摘要： A toner image fixing apparatus has a fixing roller, a pressing roller, and a heating roller which are rotatable about their own axes. The pressing roller presses a sheet carrying an unfixed toner image against the fixing roller to fix the unfixed toner image to the sheet. The heating roller is disposed on one side of the fixing roller remotely from the pressing roller. An endless heat transfer belt is trained around the heating and fixing rollers for transferring heat from a heater to heat the unfixed toner image on the sheet. A guide plate is positioned upstream of the pressing roller for guiding the sheet to enter between the fixing and pressing rollers. The heat transfer belt and the guide plate are so spaced from each other that the sheet prior to being entering between the fixing and pressing rollers is kept out of contact with the heat transfer belt. The heat transfer belt may be positioned outside of a region where the sheet guided by the guide plate possibly passes. An angle between a line segment interconnecting the centers of the heating and fixing rollers and a reference line interconnecting the centers of the fixing and pressing rollers lies in a range from 105.degree. to 255.degree.. The fixing roller is a resilient roller with an outer resilient layer. The temperatures of the fixing and pressing rollers are kept in a predetermined temperature range in a standby mode.
摘要翻译：调色剂图像定影装置具有能够围绕其自身的轴线旋转的定影辊，加压辊和加热辊。加压辊将承载未定影调色剂图像的片材压靠在定影辊上，以将未定影的调色剂图像固定在片材上。加热辊远离压辊设置在定影辊的一侧。围绕加热和定影辊围绕循环传热带进行培养，用于从加热器传递热量以加热片材上未定影的调色剂图像。引导板位于加压辊的上游，用于引导片材进入定影辊和压辊之间。传热带和引导板彼此隔开，使得在进入固定辊和加压辊之前的片材与传热带不接触。传热带可以位于由引导板引导的片材可能通过的区域的外部。互连加热和定影辊的中心的线段之间的角度以及与固定和压辊的中心相互连接的参考线位于105°至255°的范围内。定影辊是具有外部弹性层的弹性辊。在待机模式下，固定和加压辊的温度保持在预定的温度范围内。

摘要： Disclosed is an oil applying roller provided in contact with the surface of a fixing roller of an electrophotographic copying apparatus. The oil applying roller comprises a core member, an oil retaining layer and a surface layer. The surface layer has less oil retaining ability than that of the oil retaining layer. Thus the oil applying roller can supply a small amount of oil to the fixing roller stably.
