Abstract
A fixing device includes a belt, a heater, and a pressing member for forming a nip through the belt in cooperation with the heater. The nip includes a region at which a width of the nip with respect to a feeding direction of a recording material gradually increases from a longitudinal central portion toward a longitudinal end portion, and a pressure of the nip gradually increases from the longitudinal central portion toward the longitudinal end portion. A heat-conductive member includes a regulating portion for regulating movement thereof relative to a supporting member in a longitudinal direction of the heater. The regulating portion is provided in a region of the heat-conductive member corresponding to a position of the nip closer to the longitudinal end portion than to the longitudinal central portion, and a bias member is provided outside of the region of the heat-conductive member corresponding to the position of the nip.
