摘要： A separation unit is provided on a downstream side of a contact area between a belt-like rotating body and a pressure rotating body. The separation unit includes a pressure member, a guide portion and a pressure portion. The pressure member extends along a width direction of the belt-like rotating body, and presses the belt-like rotating body to deform the belt-like rotating body into a bent shape changing a course away from a surface of the pressure rotating body. The guide portion is on the pressure rotating body side of the pressure member to guide the belt-like rotating body so that an angle portion of the bent shape bites into the pressure rotating body. The pressure portion is on the surface in the pressure rotating body side, and the surface separates sequentially from the pressure rotating body in the extending direction from a center portion to an end portion.

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.
