| 1. A fixing device comprising:
a heating rotation body comprising an endless peripheral surface that moves circularly;
a heat source that heats the heating rotation body; and
a pressurization member that 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, wherein:
the pressurization member comprises:
a base material; and
a plurality of 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, and
the layer disposed just below the surface layer is grounded.
