The image forming apparatus is of a type that fixes on paper, and has a control means for controlling the image forming process, and immediately after power-on, the temperature of the fixing roller detected by the temperature detection means for temperature control is detected by the temperature of the fixing roller. Compared with a predetermined reference temperature, when the temperature of the fixing roller is lower than the reference temperature, the image forming apparatus is preparatory driven, and when the temperature of the fixing roller is equal to or higher than the reference temperature, the preparatory drive is omitted. image forming apparatus.
