Abstract
The image heating apparatus includes an endless belt, a heater placed in contact with an inner surface of the endless belt, a holder made of resin, adapted to hold the heater, and provided with a supporting space to be fitted with the heater, where a through hole is formed in a heater receiving surface of the holder at a bottom area of the supporting space; and a back-up member adapted to form a nip together with the heater to pinch and convey a recording material through the endless belt. In the bottom area, hollow portions recessed from the bottom area are provided at opposite ends in a short direction of the holder, being located at locations in a longitudinal direction of the holder different from a location in which the through hole is formed. Consequently, even if the heater heats up abnormally, heater cracks can be prevented.
