Image heating apparatus and image forming apparatus

An image heating apparatus comprising:

• a heater configured to heat an image formed on a recording material, the heater including a first heat generating block, a second heat generating block, and a third heat generating block divided in a direction orthogonal to a conveying direction of the recording material;
• a first driving element provided in a first power supply path to the first heat generating block;
• a second driving element provided in a second power supply path to the third heat generating block;
• and
• a relay configured to switch between a connected state, in which the second heat generating block and the first driving element are connected, and a disconnected state, in which the second heat generating block and the first driving element are disconnected, the relay being provided in a third power supply path that is branched from the first power supply path and that extends toward the second heat generating block.

An image heating apparatus comprising:

• a heater configured to heat an image formed on a recording material, the heater including a first heat generating block and a second heat generating block divided in a direction orthogonal to a conveying direction of the recording material;
• a first power supply path configured to connect a commercial power supply with the first heat generating block;
• a second power supply path configured to connect the commercial power supply with the second heat generating block, the second power supply path being branched from the first power supply path at a branch point;
• a first switch configured to change a connection state of the first power supply path, the first switch being provided in an area between the commercial power supply and the branch point in the first power supply path;
• a second switch configured to change a connection state of the second power supply path, the second switch being provided in the second power supply path;
• and
• a temperature detection element that detects a temperature of the first heat generating block,
• wherein the image heating apparatus does not include a switch for changing the connection state of the first power supply path in an area between the branch point and the first heat generating block in the first power supply path, and
• wherein a temperature detection element that detects a temperature of the second heat generating block is not provided.
