Abstract
A toner image fixing device for fixing a toner image carried on a support material onto the support material through heat fusing includes a fixing roller provided with a heating element and a pressure roller arranged to contact, under pressure, the fixing roller for passing the support material between the fixing roller and the pressure roller. The toner image fixing device further includes a contact and spacing mechanism for causing the pressure roller selectively to contact or to be spaced from the fixing roller through utilization of expansion and contraction of an object or substance following turning-on and turning-off of the power supply.
