An image forming apparatus includes: a conveyance motor for conveying paper; an image forming unit forms a toner image on the conveyed paper; and a fixing device having a heat roller including plural heat sources to cause the toner image to be fixed to the paper. The image forming apparatus also includes a control unit. The control unit generates a control signal that switches ON or OFF the heat sources and a signal controls the driving of the conveyance motor, and generates a mode signal that differs between a warm-up mode and a normal mode. The control unit switches ON the plural heat sources at the same time and prohibits the driving of the conveyance motor during the warm-up mode, and allows the driving of the conveyance motor and prohibits all of the plural heat sources from being switched ON at the same time during the normal mode. |
