摘要： A fixing device has a heating roller and a pressure belt. Surface hardness of the pressure belt is higher than surface hardness of the heating roller. An overall length of the pressure belt is longer than an overall length of a rubber layer of the heating roller. Both ends of the pressure belt are positioned outside both ends of the rubber layer of the heating roller. Thereby, the heating roller is improved in service life, so that the fixing device as a whole is improved in service life.

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： Fixing belt is brought into pressure-contact with the surface of fixing roller such that fixing belt rotates according to rotation of fixing roller, thereby forming, between fixing belt and fixing roller, fixing nip portion through which recording sheets pass. A pressing area of an opposing surface of pressing member contacting the surface of fixing roller via fixing belt is smaller in each end portion of the opposing surface in the axis direction of fixing roller than in a central portion of the opposing surface in the axis direction of fixing roller. This makes speed of conveying recording sheets faster in each edge portion in the width direction perpendicular to a recording sheet conveyance direction than in a central portion in the width direction. Thus, creases of recording sheets can be prevented while a recording sheet passes through fixing nip portion between fixing roller and fixing belt mutually brought into pressure-contact.

摘要： A fixing device for an image forming apparatus having low heat losses. The fixing device consists of a fixing roller and a compression roller for abutting upon it under pressure. The fixing roller and compression roller have a release layer each formed on the surface of a core metal formed of an aluminum hollow cylinder. The release layer on the surface of the fixing roller is formed of a composite material of metallic powder of good thermal conductive material such as nickel, and fluorine resin such as polytetrafluoroethylene (PTFE) and polyphenylene alkoxyether (PFA), and has spectral emissivity at a wavelength of 5 to 10 .mu.m being within a range of 0.1 to 0.65. The compression roller is provided with a release layer formed of fluorine resin like the conventional one, or the same material as the release layer on the surface of the aforesaid fixing roller, having lower spectral emissivity.
