定着装置。[Claims for Utility Model Registration] (1) In a toner fixing device that fixes a toner image by passing a sheet paper carrying a toner image between a fixing roller and a pressure roller, the pressure roller has a hollow structure. A pressure shaft whose both ends apply pressure toward the fixing roller is passed through the hollow portion, and bearings are mounted at at least three places on the pressure shaft to rotate the pressure roller. A toner fixing device, which is freely supported and further includes an eccentric portion for giving deflection to the pressure roller at at least one bearing mounting position of the pressure shaft. (2) The toner fixing device according to claim (1), further comprising an angle adjustment section for displacing the eccentric section at an arbitrary angle in the circumferential direction.
