ABSTRACT:
An image forming apparatus, for which a heated roller fixing device is employed but for which a savings in power can still be obtained, is provided. The image forming apparatus includes: a fixing device, which is a heated roller fixing device that requires pre-heating in a stand-by state; an operation panel, with which a power-saving mode transition time period can be changed; and a control part, which selects pre-heating or does not select pre-heating of the heated roller fixing device. The control part employs the power-saving mode transition time period, entered at the operation panel, to change the pre-heating or to not change the pre-heating of the heated roller fixing device.
