ABSTRACT:
An image forming apparatus is provided having a fixing device which heats a fixing roller from the surface thereof by means of an external heating device, which image forming apparatus is capable of improving fixability immediately just after a start-up and enhancing a job efficiency. An image forming apparatus includes a toner image forming section, a transfer section, a fixing device, and an interrupt control section. At least two levels are set as a job interrupt reference temperature, the interrupt control section individually selects, from among the at least two levels of job interrupt reference temperature, the level to be used for either or both of a job immediately after the start-up from a power-on and a job immediately after a return from a sleep mode, and the level(s) for other job(s), and carries out an interrupt control using the selected level of job interrupt reference temperature.
