Abstract
An image heating member for heating an image formed on a recording material includes a base material, an elastic layer which contains a thermally conductive filler of 5 μm or more in average diameter and which is provided on the base material, and a parting layer which is provided on the elastic layer so as to contact the elastic layer and which is formed of a fluorine-containing resin tube provided on the elastic layer. The fluorine-containing resin tube has 3% or more in heat contraction rate with respect to a widthwise direction of the image heating member before and after the fluorine-containing resin tube is heated and left standing in an oven at 200° C. for 30 minutes.
