ABSTRACT:
Enabling to perform the pressurization release and the fixture release simultaneously by one action when taking out the fixing device from the image forming device for removing the jammed paper and the like. In a fixing device comprising a pressurization roll being pressurized by the act of a pressurization lever and a spring against a heat roll, a release lever is further mounted rotatably which comprises a cam for rotating the pressurization lever against the direction of force from the spring. On the release lever is mounted a connecting pin, and the connecting pin is linked to and rotates the fixing lever which is also mounted rotatably. The fixing lever is forced toward the fixing direction by a spring, wherein a fixing piece is inserted to a fixing slit of a mounting stage formed on the image forming device body for positioning thereto. By rotating the release lever, the pressurization lever could be rotated to the direction for releasing the pressure, and simultaneously, the fixing lever is linked thereto and rotated to the direction for releasing the fixing piece from the fixing slit, thereby performing the pressurization release and fixture release by a single operation.
