摘要： An image forming apparatus is provided. The image forming apparatus includes an image forming section, an intermediate transfer section, a secondary transfer section, a fixing section, a power source, a voltage detection section, a temperature detection section, and a fixing section control circuit. The fixing section control circuit includes a switching control section, a voltage judgment section, a temperature judgment section, and a preparation control section. When the switching control section switches the current conduction state to the heat source and the driving section from an off conduction state to an on conduction state and the voltage judgment section judges to be less than a threshold voltage, the preparation control section controls the preparation operation of the heating section such that the switching control section continues the on conduction state over a given idle time after the temperature judgment section has judged to be a preset temperature or higher.

摘要： A fixing device which can reduce an overshoot of the surface temperature of a main heating section without lengthening a warming-up period of time, an image forming apparatus equipped therewith, and a recording medium on which is recorded the temperature control program are provided. In a standby mode, control is performed to stop an operation of a halogen lamp which is an internal heat source, when a surface temperature of a heating roller reaches a certain temperature lower than a target temperature, or when the operating period of time of the halogen lamp reaches a certain period of time. By so doing, as the heating roller ceases to be heated at a point at which it reaches a temperature lower than the target temperature, it is possible to reduce the overshoot of the surface temperature of the heating roller.

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.

Accordingly, a belt substrate is exposed and has contact with the cleaning member. This suppresses the occurrence of offset in a fixing device including (i) the external heating belt for having contact with the surface of the fixing roller so as to heat a fixing roller, and (ii) the cleaning member having contact with the external heating belt.

摘要： A fixing device of the present invention includes: an external heating belt which is to contact with a surface of a fixing roller so as to heat up the fixing roller; and a cleaning member (a scraper and/or cleaning pad) which is to contact with the external heating belt. The cleaning pad which is impregnated with silicone oil is to contact with a surface of the external heating belt, thereby applying the silicone oil (release agent) to the surface of the external heating belt. This makes it possible to prevent generation of an offset.
