摘要： A heat-resistant sheet is provided between a fusing roller and a pressing member made of a resilient material. The heat-resistant sheet is composed of a glass fiber substrate coated with or impregnating a fluororesin having good mold lubrication and heat-resistance, such as PFA and PTFE. A paper having a pre-fused toner image is carried through a section between the fusing roller and heat-resistant sheet. Accordingly, wear or separation of the heat-resistant sheet caused by friction with the fusing roller can be prevented, thereby improving durability of the heat-resistant sheet.

摘要： A fixing device having a fixing belt which satisfies 42.2≧ER≧0.1044×D×μ−0.5174, where: D represents an inner diameter of the fixing belt; A represents a second inner diameter of the fixing belt; ER represents an elongation rate of the fixing belt and is formulated as ER=(A−D)/D×100; and μ represents a coefficient of kinetic friction between the fixing belt and the fixing roller. The fixing device is thus arranged so that the fixing belt is driven by the fixing roller to rotate in a state where the pressing roller is separated from the fixing belt. This makes it possible to lengthen a life of a fixing belt, to shorten a warm-up time, and to reduce power consumption in a fixing device using a belt fixing method.

摘要： In a fixing device including (i) an external heat belt which abuts against a surface of a fixing roller so as to heat the fixing roller and (ii) a cleaning member which abuts against the external heat belt, a fixing temperature, which is a surface temperature of the fixing roller during a fixing process, is set per group into which recording media to be subjected to the fixing process are divided according to their widths in a direction of a rotary axis of the fixing roller, in such a way that the fixing temperature is set to a lower temperature for a group of narrower widths. This makes it possible to prevent a reduction in releasability of the fixing roller caused by a material, which is scraped off from the external heat belt by the cleaning member and then adhered to the fixing roller, thereby preventing the high-temperature offset.
