Claims

[Claims for Utility Model Registration] A plurality of fixing means fixing a developer image on the recording medium by pinching the recording medium;
a second housing, wherein the other fixing means is attached to a fixed position, and the second fixing means is attached to be movable angularly with respect to a predetermined rotational center position of the first housing such that the other fixing means is moved toward/away from the one fixing means; A fixing device comprising: a housing; a swinging member that is provided integrally with the other fixing means and swings according to the angular displacement of the other fixing means; the swinging member is stopped at a plurality of stable positions; a drive piece that angularly displaces the recording medium to a stable position; a paper ejection device that ejects the recording medium after fixing to the outside of the machine; and an ejection device that includes a cover member to which the drive piece and the paper ejection means are attached; When the cover member is in a closed state with respect to the fixing device, the swinging member stops the other fixing means in a stable position close to one fixing means, and when the cover member is in an open state, the swinging member stops the other fixing means. A mounting structure for a fixing device, characterized in that the fixing device is stopped at a stable position separated from one of the fixing means.
