Abstract (en)

A fixing device (7) includes an endless fixing belt (22), a heater (31), a pressing member (23), a nip formation pad (32) disposed inside a loop of the fixing belt (22) and configured to contact the pressing member (23) to form a fixing nip, and a reflector (34) disposed inside the loop of the fixing belt (22) and configured to reflect heat from the heater (31). The nip formation pad (32) has a wider width at a portion corresponding to a central region in a longitudinal direction than an end portion of the nip formation pad (32) in the longitudinal direction. The reflector (34) extends in a longitudinal direction of the nip formation pad (32) and has an opening (34k) opened to the nip formation pad (32). The opening (34k) has a wider width at a portion corresponding to the central region in the longitudinal direction than a width at an end portion of the reflector (34) in the longitudinal direction; and corresponding image forming apparatus.
