The rubber layer is subjected to surface processing by spraying the surface with a solution containing an isocyanate compound and heating. The amount of the electronic conductive agent added to the rubber base material is limited so that a volume resistivity when only the electronic conductive agent is added to the rubber base material is 1.46×106 ?·cm or greater. In addition, the amount of the added ionic conductive agent is increased so that a volume resistivity when the electronic conductive agent and the ionic conductive agent are added to the rubber base material is 1.93×106 ?·cm or less.

  • Patent number: 7668473
    Abstract: There are provided a fixing device and an image forming apparatus capable of reducing a sensing error of a surface temperature of a heating roller. The fixing device includes a temperature sensor for sensing the surface temperature of the heating roller, and a temperature calculation circuit. The temperature calculation circuit includes a noise removal prevention circuit. The temperature sensor includes an infrared ray sensing thermistor and a compensation thermistor, and the noise removal prevention circuit prevents removal of a part of an AC component (such as a high frequency component in a noise) included in a difference between outputs (difference output) of the infrared ray sensing thermistor and the compensation thermistor. Thus, the AC component is prevented from being offset when the difference outputs are averaged, thus reducing the sensing error of the surface temperature of the heating roller based on the average value of the difference outputs.
