ABSTRACT:
A fixing device provided with a heating roller having heating means, a pressure roller for fixing a toner image by transporting a toner image bearing member in cooperation with the heating roller, drive mechanism for rotating the heating roller and pressure roller, and a control for initiating the rotation of the heating roller and pressure roller when the heating roller reaches a determined surface temperature or at a determined time after the heating means is activated, wherein the heating means is so activated at the turning on of the power supply as to reduce the waiting time required by the rollers to reach a satisfactory fixing temperature, thus preventing defective fixing at the start of operation.
