Abstract
A fixing apparatus comprises a fixing device which fixes a developer image by passing a toner image fixing material between a heating rotary body and a pressing rotary body which are pressed and contacted, wherein at least one of the heating rotary body and pressing rotary body has an elastic foam layer with a rubber hardness of 20-50 degrees, and a conductor layer formed on the surface of the elastic foam layer.
Claims16
A fixing apparatus comprising:
- a fixing device which fixes a developer image by passing a fixing material with a developer image between a heating rotary body and a pressing rotary body which are pressed and contacted;
- wherein
- at least one of the heating rotary body and pressing rotary body has an elastic foam layer with a rubber hardness of 20-50 degrees, and a conductor layer formed on the surface of the elastic foam layer.
A fixing apparatus comprising:
- a fixing device which fixes a developer image by passing a fixing material with a developer image between a heating rotary body and a pressing rotary body which are pressed and contacted;
- wherein
- at least one of the heating rotary body and pressing rotary body has an elastic foam layer with a modulus of elasticity of 3.5×10−4 or less, and a conductor layer formed on the surface of the elastic foam layer.
A fixing apparatus comprising:
- a fixing device which fixes a developer image by passing a fixing material with a developer image between a heating rotary body and a pressing rotary body which are pressed and contacted, wherein
- at least one of the heating rotary body and pressing rotary body has an elastic foam layer, and a conductor layer formed on and in one body with the surface of the elastic foam layer.
A fixing apparatus comprising:
- a fixing device which fixes a developer image by passing a fixing material with a developer image between a heating rotary body and a pressing rotary body which are pressed and contacted;
- wherein
- at least one of the heating rotary body and pressing rotary body has an elastic foam layer, and a conductor layer formed on the surface of the elastic foam layer, and has different outside diameters at the center in the axial direction and at both ends.
