Abstract

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.

First claim

What is claimed is:

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 provi…
