Abstract:
In a fixing apparatus having a heater that can selectively heat a plurality of heating blocks, which are divided in the longitudinal direction of a substrate, an power supply control portion corrects the amount of current to be supplied to a plurality of heat generating elements, based on the temperatures detected by each of a plurality of temperature detecting portions, so that a difference of a temperature rising amount per unit time among the heating blocks becomes small when the fixing apparatus starts up.

Claim (Index 1):
An image heating apparatus, comprising:\n an image heating portion that includes a heater constituted of a substrate and a plurality of heat generating elements disposed on the substrate in a longitudinal direction of the substrate, and that is configured to heat an image formed on a recording material by using the heat of the heater; a power supply control portion configured to control power to be supplied to the plurality of heat generating elements so as to selectively heat a plurality of heating regions corresponding to the plurality of heat generating elements respectively; a plurality of temperature detecting portions configured to detect temperature of each of the plurality of heating regions; and a current amount correcting portion configured to correct an amount of current that the power supply control portion supplies to the plurality of heat generating elements, wherein the current amount correcting portion corrects the current amount, based on the temperature detected by each of the plurality of temperature detecting portions, so that a difference of a temperature rising amount per unit time among the plurality of heating regions at the start of the image heating portion becomes small.
