Abstract
An image heating apparatus includes a belt including a heat generating layer for generating heat by energization and including a power receiving portion which has electroconductivity and is electrically connected to the heat generating layer; a stationary back-up member, provided inside the belt, for sliding on an inner peripheral surface of the belt; a pressing member for pressing the belt against the back-up member to form a nip in which a recording material is to be nip-conveyed between the belt and itself; and an electroconductive portion, provided on the back-up member, for supplying electric power to the power receiving portion by being electrically connected to the power receiving portion.
Claims11
An image heating apparatus comprising:
- an endless belt including an insulative base layer, a heat generating layer provided on said base layer and configured to generate heat for heating an image on a sheet at a nip portion, and an electroconductive power receiving portion configured to receive electric power and for supplying the received electric power to said heat generating layer;
- a driving roller configured to drive said endless belt and to form the nip portion cooperatively with said endless belt;
- a pressing pad provided inside said endless belt and configured to press said endless belt toward said driving roller;
- and
- an electroconductive power supplying portion, provided on a surface of said pressing pad facing said endless belt and configured to supply the electric power to said electroconductive power receiving portion.
