徴とする定着装置。 It has a heating roller and a pressure roller that rotate in pressure contact with each other, as well as a conveyance roller that conveys the paper sent out between both rollers, and the entire body is detachable from the installation machine. In a fixing device that is installed in a fixing device, the conveyance roller support frame that supports the conveyance roller is rotatable with respect to the pressure roller support frame that removably supports the pressure roller, and the pressure roller is supported by its own weight. It is attached so as to be biased to rotate toward the frame, and has a heating roller at a predetermined position on the transport roller support frame and a paper peeling claw that contacts one surface of the pressure roller. The heating roller support frame to be supported is attached to the pressure roller support frame so as to be rotatable about a fulcrum located on the opposite side of the conveyance roller support frame, and the pressure roller support frame is rotated at a predetermined position. 1. A fixing device characterized in that a spring is removably attached between the position and a predetermined position of the heating roller support frame for strongly pressing the pressure roller against the heating roller.
