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.
Claims11
A method of manufacturing a heat generating roller, the method comprising:
- 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.
A heat generating roller comprising:
- a base member made of metal;
- a heat generating portion made of a material that generates heat when energized;
- and
- an insulating portion provided between the base member and the heat generating portion and that electrically insulates the base member and the heat generating portion from each other, the insulating portion being obtained by providing a cylinder of poly-ether-ether-ketone resin over the base member and fixing the cylinder to the base member by heat-shrinking the cylinder.
