Rotational heating member, and image heating apparatus having rotational heating member

摘要

An image heating rotatable member for heating an image on a recording material, comprising a base layer; a heat generation layer, provided on the base layer, for generating heat by being supplied with electric power; an electrode layer, provided outside of the heat generation layer with respect to a widthwise direction and having an electric resistance which is smaller than that of the heat generation layer, for supplying the electric power to heat generation layer; an elastic layer provided on the electrode layer and having a length longer than that of the electrode layer measured in the widthwise direction; and a parting layer provided on the elastic layer and having a length which is substantially equal to the length of the electrode layer measured in the widthwise direction.

1. An endless fixing belt usable in an electrophotographic image forming apparatus, comprising:
a heat generation layer configured to generate heat by being supplied with electric power; a first electrode layer provided so as to be electrically connected with one end of said heat generation layer in a widthwise direction of said belt, and having an electrical resistance which is smaller than that of said heat generation layer; a second electrode layer provided so as to be electrically connected with the other end of said heat generation layer in the widthwise direction, and having an electrical resistance which is smaller than that of said heat generation layer; an elastic layer provided on said heat generation layer so as to expose at least one area of said first electrode layer and at least one area of said second electrode layer in the widthwise direction; and a fluorine resin layer provided on said elastic layer so as to expose the at least one area of said first electrode layer and the at least one area of said second electrode layer.
