Claims

[Claims for Utility Model Registration] 1. A heat roller fixing device that separates a sheet of paper that has been pressed and fixed against the fixing roller from the fixing roller by a separation claw that presses against the fixing roller,
The separating claw is swingably mounted so as to partially traverse the paper discharge path so that the separating claw is pushed to a position away from the fixing roller by the paper immediately after separation. , heat roller fixing device. 2. The heat roller fixing device according to claim 1, further comprising cleaning means for cleaning the tip of the separating claw when the separating claw is separated from the fixing roller.
