Image heating apparatus and image forming apparatus that control electrical power supplied to first and second heat generating blocks

An image heating apparatus that heats an image formed on a recording material, the image heating apparatus comprising:

• a heater including a first heat generating block, and a second heat generating block disposed adjacent to the first heat generating block in a longitudinal direction of the heater, the longitudinal direction being orthogonal to a conveying direction of the recording material;
• and
• a power control portion that controls electrical power to be supplied to the first heating block and the second heat generating block, the power control portion being capable of controlling the electrical power to be supplied to the first heating block and the second heat generating block independently,
• wherein, when the recording material passes the position of the heater, and, in the longitudinal direction, when an entire range in which the second heat generating block is provided is a range in which the recording material passes and only a portion of a range in which the first heat generating block is provided is a range in which the recording material passes, the power control portion controls the electrical power to be supplied to the first heating block and to the second heat generating block so that electrical power Wd supplied to the first heat generating block is less than electrical power Wc supplied to the second heat generating block.
