An image heating apparatus for heating an image formed on a recording material includes a heating device which heats the image formed on the recording material, and a pressure roller which forms a nip portion in cooperation with the heating device, with the recording material being conveyed in the nip portion. The pressure roller has a heat resistive rubber in which acicular fillers with a thermal conductivity of more than 300 W/mK are dispersed in a rate of 12 to 26 volume percentage. An image heating apparatus is achieved which prevents increasing the temperature at the area through which a recording material does not pass.
