Abstract
A fixing apparatus, for fixing a toner on a recording material by using Joule heat which is generated by applying a voltage across the conductors or across the electrodes to supply a current mostly to a fixing portion, (I) comprises a heating device having a first conductive layer, a pressure-sensitive conductive resin layer which is formed on the first conductive layer, and a second conductive layer formed on the pressure-sensitive conductive resin layer, (II) comprises a heating device having a first conductor and a fixing sheet substantially made of a pressure-sensitive conductive resin layer and a second conductive layer, or (III) comprises a heating device having a fixing sheet made of a heat-generating resistor and first and second electrodes insulated from each other.
