    摘要： A fixing device incorporated in an image forming apparatus for fixing a toner image on recording paper, including a fixing roller in which a cylindrical core and a heater are installed in the roller, a pressure roller held in pressured contact with the fixing roller, and a reinforcing device used to preserve a cylindrical shape of the cylindrical core. The reinforcing device includes a circular plate and a contacting member which is provided along an edge of the circular plate and which has a contacting portion held in contact with an inner surface of the cylindrical core.

    摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.

    摘要： A fixing device for an image forming apparatus of the present invention includes an endless belt passed over a plurality of members for conveying a sheet in contact with a toner image carried thereon. A pressing member faces the above members with the intermediary of the belt. A first member, which is one of the plurality of members, constitutes a heating member for heating the belt. A second member, which is another one of the members, faces the pressing member with the intermediary of the belt. A third member, which is another one of the members, constitutes a stationary member facing the pressing member with the intermediary of the belt. The pressing member and first member and the pressing member and second member respectively form a first and a second nip therebetween. The toner image on the sheet is fixed by being sequentially conveyed via the first and second nips.
