摘要:
The present invention relates to an image heating apparatus that includes a heater including a plurality of independently controllable heating blocks in a longitudinal direction thereof, each including a first conductor, a second conductor, and a heating element. At least one of electrodes corresponding to the respective heating blocks is disposed in an area where the heating element is located in the longitudinal direction on a second surface of the heater that is opposite to a first surface that comes into contact with an endless belt. An electrical contact is arranged so as to face the second surface of the heater. An overheating occurring in a no-media passage portion when an image formed on a recording material having a small size is heated is suppressed or reduced.
