Fixing apparatus and image forming apparatus that set target temperatures of heat generating elements for heating a developer image in each of a plurality of regions

A fixing apparatus comprising:

• a plurality of heat generating elements for heating a developer image formed on a recording medium corresponding to a plurality of heating regions, the heat generating elements fixing the developer image formed on the recording medium to the recording medium by heating,
• wherein a first target temperature of the heat generating elements for heating the developer image is set based on a developer amount per unit area of the developer image in each of the plurality of heating regions, and the temperature of the heat generating elements is controlled to the first target temperature, and
• wherein, in a case in which a developer image includes a developer image that is formed over two adjacent heating regions of the plurality of heating regions and the amount of developer per unit area of one portion thereof that is included in one of the two adjacent heating regions and the amount of developer per unit area of the other portion thereof that is included in the other of the two adjacent heating regions are substantially the same and a difference between the first target temperatures for the two adjacent heating regions is outside of a predetermined range, the first target temperature for one of the two adjacent heating regions is corrected to a second target temperature, which is higher than the first target temperature, so that the difference between the first target temperatures for the two adjacent heating regions is within the predetermined range.
