摘要：
A heat conduction unit includes a flexible endless belt, a heat conductor disposed in proximity to an inner circumferential face of the endless belt and having a cross-section substantially identical to a cross-section of the endless belt, a heat source that heats the heat conductor to heat the endless belt, a pressing roller disposed opposite the heat conductor to rotate the endless belt in accordance with rotation of the pressing roller, a nip formation member disposed opposite the pressing roller and within a loop formed by the endless belt to form a nip between the endless belt and the pressing roller, and a pushing member disposed within the loop to support the nip formation member. The heat conductor has at least two different cross-sectional shapes perpendicular to a long direction of the heat conductor at different positions in the long direction of the heat conductor.
