Abstract
A method of manufacturing a heat generating roller includes forming an insulating portion on a surface of a metal base member by providing poly-ether-ether-ketone resin over the surface of the base member and heating the poly-ether-ether-ketone resin, the poly-ether-ether-ketone resin being electrically insulating and heat-shrinkable; and forming a heat generating portion on a surface of the insulating portion, the heat generating portion generating heat when energized.
