Abstract
An image heating device for heating a toner image while nip-conveying a recording material, in a nip, on which the toner image is carried, includes a heating member; and a pressing roller, including an elastic layer, for forming the nip in contact with the heating member. The elastic layer of the pressing roller includes a thermosetting silicon rubber containing a thermal conductive filler. The thermosetting silicon rubber includes pore portions formed with resin microballoons and a pore connecting portion for connecting the pore portions. The elastic layer has a thermal conductivity of 0.15 W/mK to 0.5 W/mK.
