ABSTRACT:
A roll for fixing a toner image formed on a support sheet in electrophotography comprising a plurality of layers made of a resilient material and arranged around a core disposed about the center axis of the roll. The resilient material layer disposed nearer to the core is electrically conductive and serves to make the roll function as a heating roll. It has a higher hardness than the resilient material layers remote from the core.
