摘要:
A heat-producing element for a fixing device to carry out heat-fixing after a toner image having been formed using a pulverized toner is transferred on an image support, a heat-producing element for a fixing device in which a thin-leaf graphite-pulverized material of a volume specific resistance of 10−6 Ω·cm to less than 10−2 Ω·cm is incorporated in a heat-resistant resin as a conductive material.
摘要:
The method of forming an electrode in a heat generating fixing belt entails supplying a colloid liquid where metal nano-particles are dispersed in a liquid medium, on the surface of an electrically resistant heat generating layer and forming a plated film by an electroless plating method using the metal nano-particles as a catalyst. The electrically resistant heat generating layer is composed of a resin. In this manner, a pair of electrodes are formed on the surface of the electrically resistant heat generating layer. The electrodes supply electric current to the electrically resistant heat generating layer. The heat generating fixing belt can maintain an initial conduction resistance for a long period of time.
