摘要：
A heat fixing device includes a rotatable member for heating, a pressing roller configured to form a fixing nip portion that nips and conveys a recording material bearing a toner image, and a cooling fan configured to cool a recording material non-passing region in the rotatable member for heating in a direction orthogonal to a recording material conveying direction, wherein the pressing roller includes a rubber layer, between a cored bar and a release layer, containing a needle-shaped heat conductive filler oriented in a roller axis direction.
