Abstract
A fixing apparatus for fixing a toner image on a recording material includes a heating member; an opposing member which nips the recording material; and a control unit that sets a target temperature of the heating member. The control unit acquires toner amount information for each of a plurality of regions which are separated in a direction perpendicular to the conveying direction, and sets, based on (i) a first value which is based on toner amount information in each region of a first toner image formed on a first recording material, (ii) a conveying interval between the first and a second recording material, and (iii) a second value which is based on toner amount information in each region of a second toner image formed on the second recording material, the control unit sets the target temperature to heat the second recording material.
