Abstract
A fixing device includes an endless belt of which a surface layer is elastically deformable and a pressurizing section that is in pressure contact with the belt and that forms a nip portion, in which a maximum deformation position at which a degree of deformation of a surface of the belt is maximal is set to a position different from a maximum pressure position at which a pressurizing force of the belt is maximal.
Claims17
A fixing device comprising:
- an endless belt of which a surface layer is elastically deformable;
- and
- a pressurizing section that is in pressure contact with the belt and that forms a nip portion,
- wherein a maximum deformation position at which a degree of deformation of a surface of the belt is maximal is set to a position different from a maximum pressure position at which a pressurizing force of the belt is maximal,
- wherein the fixing device further comprises a regulating section that regulates a traveling position of the belt such that the maximum deformation position at which the degree of deformation of the surface of the belt is maximal is made different from the maximum pressure position at which the pressurizing force of the belt is maximal,
- wherein the regulating section forms a stepped portion retracted by a direction away from the pressurizing section.
