摘要： A first pad has a first nip forming surface which extends in a direction X. An angle formed between an end portion of the first nip forming surface and an XZ plane is smaller than an angle formed between a central portion of the first nip forming surface and the XZ plane, where the XZ plane is formed on a downstream side of the first nip forming surface. Thereby, a fixing device is provided which suppresses generation of wrinkles on a recording material when the fixing device fixes toner on the recording material and conveys it.

摘要： A belt-type fixing device is provided by which driving torque for a fixing belt can be reduced.The belt-type fixing device has the fixing belt wound around a heating roller and around a nip forming member, and has a pressurizing roller that is in pressure contact with the nip forming member with the fixing belt interposed between. A surface of the nip forming member that is opposite to the pressurizing roller is configured as a curved surface extending along an outer circumferential surface of the pressurizing roller so that a pressure distribution in a fixing nip is made generally flat with respect to a paper feeding direction. By rotational drive of the pressurizing roller, the fixing belt is rotated while being slid on the nip forming member. Contact area between the fixing belt and the nip forming member outside the fixing nip is smaller on nip entrance side than on nip exit side.

摘要： An induction heating type fixing apparatus comprises a fixing sleeve formed of a flexible thin electrically conductive magnetic material, a coil for producing an induced eddy current in the fixing sleeve to generate heat therein, a holder adapted to retain the coil and disposed stationarily in the fixing sleeve, and a pressing roller pressed against the holder through the fixing sleeve. A sheet carrying thereon an unfixed toner is conveyed as nipped between the fixing sleeve and the pressing roller. The toner on the sheet is melted by the heat of the sleeve itself and exposed to the pressure exerted between the holder and the pressing roller and fixed on the sheet. The holder is provided with a separating member adapted to effect the curvature separation of the sheet from the fixing sleeve. The holder is further provided with a heat-diffusing member made of a material with good thermal conductivity characteristics and non-magnetic properties.
