Image forming apparatus that controls a setting used for temperature control based on thermal history information

Provided is an image forming apparatus, having: a fixing portion which includes a plurality of heating elements and heats a plurality of heating regions independently using the plurality of heating elements respectively so as to fix an image formed on a recording material to the recording material; an acquiring portion which acquires information on an image formed on a recording material, and thermal history information on a plurality of regions corresponding to the plurality of heating regions in the fixing portion respectively; and a control portion which controls heating of the heating regions by the fixing portion. The control portion corrects a control setting used for the temperature control of the heating regions, based on the thermal history information on a region of the fixing portion corresponding to a thermal history calculating region generated by dividing each of the heating regions in a direction orthogonal to the transport direction.
