摘要： A fixing device includes a heating rotation body, a heat source and a pressurization member. The heating rotation body has an endless peripheral surface that moves circularly. The heat source heats the heating rotation body. The pressurization member is in pressure-contact with the peripheral surface of the heating rotation body to press a recording medium, which passes through a nip between the pressurization member and the heating rotation body, against the peripheral surface of the heating rotation body. The pressurization member includes a base material and plural layers deposited on the base material. A volume resistance of a surface layer forming a surface of the pressurization member is larger than that of a layer disposed just below the surface layer. The layer disposed just below the surface layer is grounded.
