Image forming device equipped with a releasable fixing device

摘要

Enabling to perform the pressurization release and the fixture release simultaneously by one action when taking out the fixing device 4 from the image forming device for removing the jammed paper and the like. In a fixing device 4 comprising a pressurization roll 42 being pressurized by the act of a pressurization lever 50 and a spring 52 against a heat roll 41, a release lever 53 is further mounted rotatably which comprises a cam 53a for rotating the pressurization lever 50 against the direction of force from the spring 52. On the release lever 53 is mounted a connecting pin 53b, and the connecting pin 53b is linked to and rotates the fixing lever 54 which is also mounted rotatably. The fixing lever 54 is forced toward the fixing direction by a spring 56, wherein a fixing piece 54c is inserted to a fixing slit 57b of a mounting stage 57 formed on the image forming device body for positioning thereto. By rotating the release lever 53, the pressurization lever 50 could be rotated to the direction for releasing the pressure, and simultaneously, the fixing lever 54 is linked thereto and rotated to the direction for releasing the fixing piece 54c from the fixing slit 57b, thereby performing the pressurization release and fixture release by a single operation.
