Abstract (en)

A fixing device (5) includes a fixing member (22), a pressing member (23), a nip formation member (32) pressed by the pressing member (23) via the fixing member (22), a plurality of heat generators (31a, 31b), and a shield (34) inside the fixing member (22) to block heat from the heat generators (31a, 31b). The plurality of heat generators (31a, 31b) includes one heat generator (31b) close to the nip formation member (32) and the other heat generator (31a) farther from the nip formation member (32) than the one heat generator (31b) in a direction that is perpendicular to a recording medium conveyance direction and is not a width direction of the fixing member (22). The shield (34) has a part disposed between the one heat generator (31b) and the other heat generator (31a) in a cross section that intersects the width direction of the fixing member (22).
