Abstract (en)
A fixing device (5) includes a rotatable endless fixing belt (21), a pressing member (22) configured to press the fixing belt (21), a heater (23) disposed inside a loop of the fixing belt (21) and configured to heat the fixing belt (21), and a nip formation member (24) disposed inside the loop of the fixing belt (21) and configured to come into contact with the pressing member (22) via the fixing belt (21) to form a fixing nip. In a longitudinal direction of the heater (23), the heater (23) has a low heat generation area (23a) that generates a smaller amount of heat than another area of the heater (23). The nip formation member (24) has an elongated portion (242) that extends upstream from the fixing nip in a rotation direction of the fixing belt (21). The elongated portion (242) has the longest part (242a) positioned corresponding to the low heat generation area in the longitudinal direction.
