Abstract
PURPOSE:To prevent a wrinkle, etc. from being generated on a form, by executing immediately a rotation of a pressure roller, in a state that a switch of a copying machine main body is turned on, and heating uniformly the pressure roller. CONSTITUTION:When a start switch of a copying machine main body is turned on, simultaneously, an internal heating member 11 provided on a heating roller 10 of a fixing device 1 becomes ON, and a surface temperature of the heating roller 10 rises gradually. ON the other hand, as soon as the internal heating member 11 of the heating roller 10 becomes ON, driving of a pressure roller 15 is started. Accordingly, as a temperature of the heating roller 10 rises, the pressure roller 15 receives heat from the heating roller 10 and heated uniformly. In such a way, the generation of an ununiform expansion of the pressure roller 15 is prevented, uniform carrying force works on a form 5, and it is prevented that a wrinkle is generated on the form 5.
