Abstract text

The present invention provides a fixing member having a heat resistant resin layer, a metal layer having two or more layers, and a releasing layer, in this order from the inner peripheral side, wherein a specific resistance of the metal layer disposed at the outer peripheral side is larger than a specific resistance of the metal layer disposed at the inner peripheral side in the at least two metal layers, and a modulus of an internal stress of the metal layer disposed at the outer peripheral side is 5 kg/mm² or less. Further, a fixing device includes the fixing member, an electromagnetic induction heating device in which an electric field is applied to the fixing member, and a press member which press-contact the surface of a releasing layer of the fixing member. Furthermore, an image forming device having this fixing device is provided.
