項２記載の定着装置の排紙機構。[Scope of Claim for Utility Model Registration] (1) A separating claw that is rotatably provided on the paper ejection side of the fixing roller, and when the claw is rotated, the claw approaches the fixing roller and separates the recording paper from the fixing roller; A paper ejection unit that rotatably supports the separation claw and can be opened and closed to close and release the paper ejection side of the fixing roller; and a paper ejection unit that is interposed between the paper ejection unit and the separation claw and that opens and closes the paper ejection unit. A sheet ejection mechanism for a fixing device, comprising: an elastic member that reverses the urging direction so that the claw portion of the separation claw approaches and separates from the fixing roller in conjunction with the above. (2) The separating claw engages with a member on the apparatus main body side and rotates when the paper ejecting unit is opened and closed, and the rotation of the separating claw displaces the attachment point of the elastic member. 1. A paper ejection mechanism of the fixing device according to 1. (3) The paper ejecting mechanism of the fixing device according to claim 2, wherein the elastic member is a tension spring whose end portion is displaced by rotation of the separation claw.
