FIXING DEVICE, AND IMAGE FORMING APPARATUS

摘要

Provided is a fixing device including a heating rotating body that heats a toner image formed on a recording medium, a pressurizing rotating body including an endless belt that is placed in such a manner that an outer circumferential surface thereof faces the heating rotating body, a first pressurizing member that is placed on a side of an inner circumferential surface of the endless belt and forms a fixing nip portion between the endless belt and the heating rotating body, and a second pressurizing member that guides the recording medium so that the recording medium comes into contact with the heating rotating body on an upstream side of the fixing nip portion in a transportation direction of the recording medium, and a releasing unit that releases pressure contact of the pressurizing rotating body that is in pressure contact with heating rotating body.

主权项

1. A fixing device comprising:
a heating rotating body that heats a toner image formed on a recording medium; a pressurizing rotating body including:
an endless belt that is placed in such a manner that an outer circumferential surface thereof faces the heating rotating body;a first pressurizing member that is placed on a side of an inner circumferential surface of the endless belt and forms a fixing nip portion between the endless belt and the heating rotating body by pressing the outer circumferential surface of the endless belt to the heating rotating body; anda second pressurizing member that guides the recording medium so that the recording medium comes into contact with the heating rotating body on an upstream side of the fixing nip portion in a transportation direction of the recording medium by pressing the endless belt to the heating rotating body on the upstream side of the fixing nip portion of the side of the inner circumferential surface of the endless belt in the transportation direction of the recording medium; and a releasing unit that releases pressure contact of the pressurizing rotating body that is in pressure contact with heating rotating body, wherein the second pressurizing member is movably supported in a opposite direction opposite to a direction in which the second pressurizing member presses the pressurizing rotating body when the pressure contact of the pressurizing rotating body is released by the releasing unit.
