の加圧解除機構。 One end of the pressure arm that supports the pressure roller facing the fixing roller is rotatably supported on the fuser side plate, which has one end rotatably supported on the machine body, and the other end is rotatably supported on the fuser side plate. A pressure spring is interposed between them, and the fixing device side plate is rotated in a direction that compresses the pressure spring, so that the fixing roller and the pressure roller, which are pivotally supported by the fixing device side plate, are brought into pressure contact with each other. A fixing device characterized in that the fixing roller is maintained by engagement between a lock lever provided on a side plate of the device and a fixing pin provided on the body, and the pressure contact between the fixing roller and the pressure roller is released by disengaging the lock lever from the fixing pin. Pressurization release mechanism of the vessel.
