Abstract
An image heating device includes a cylindrical film; a heater contacted to an inner surface of the film, wherein the heater includes a substrate, a heat generating resistor provided on the substrate, and an insulating layer for covering the heat generating resistor and is contacted to the film; and a pressing member for pressing the film against the heater to form a nip, between itself and the film, in which a recording material carrying thereon an image is to be nip-conveyed. The heater includes an electroconductive layer, which is grounded, provided at a position between and remote from a film-side surface of the insulating layer and the heat generating resistor.

An image heating device comprising:
- a cylindrical film;
- a heater contacted to an inner surface of said film, wherein said heater includes a substrate, a heat generating resistor provided on the substrate, and an insulating layer for covering the heat generating resistor and is contacted to said film;
- and
- a pressing member for pressing said film against said heater to form a nip, between itself and said film, in which a recording material carrying thereon an image is to be nip-conveyed,
- wherein said heater includes an electroconductive layer, which is grounded, provided at a position between and remote from a film-side surface of the insulating layer and the heat generating resistor.
A heater comprising:
- a substrate;
- a heat generating resistor provided on said substrate;
- an insulating layer for covering said heat generating resistor;
- and
- an electroconductive layer provided at a position between and remote from a surface of said insulating layer and said heat generating resistor.
An image heating device comprising:
- a cylindrical film;
- a heater contacted to an inner surface of said film, wherein said heater includes a substrate, a heat generating resistor provided on the substrate, and an insulating layer provided on the substrate at a surface opposite from a surface at which the heat generating resistor is provided on the substrate, and is contacted to said film;
- and
- a pressing member for pressing said film against said heater to form a nip, between itself and said film, in which a recording material carrying thereon an image is to be nip-conveyed,
- wherein said heater includes an electroconductive layer, which is grounded, provided at a position the substrate and insulating layer.
A heater comprising:
- a substrate;
- a heat generating resistor provided on said substrate;
- an insulating layer provided on said substrate at a surface opposite from a surface at which said heat generating resistor is provided on said substrate;
- and
- an electroconductive layer provided at a position between said substrate and said insulating layer.
