Abstract
An image fixing apparatus includes a heater; a film movable with a recording material, in which the recording material has a visualized image which is heated through the film by heat from the heater; and the film has a heat resistive resin base layer containing inorganic electrically insulative filler material and a parting layer containing electrically conductive filler material.
Claims12
An image fixing apparatus, comprising:
- a heater having at least generating resistor for generating heat upon electric power supply and a protection layer for protecting said heat generating resistor;
- and
- a resin film movable with one surface in contact with said protection layer and the other surface in contact with a recording material having a visualized image, said film comprising a heat resistive resin base layer contactable to said protection layer and a parting layer thereon contactable to said recording material;
- wherein said base and parting layer comprise filler materials, and the filler material in said base layer has a higher resistivity than the filler material in said parting layer.
