Abstract
A fixing device includes a fixing belt that is endless and rotates in a rotation direction. A pressure rotator presses against the fixing belt to form a nip between the fixing belt and the pressure rotator. A heater is disposed opposite an inner circumferential surface of the fixing belt and heats the fixing belt. A contact member contacts the fixing belt partially in a longitudinal direction of the fixing belt. A holder holds the heater. The heater contacts the holder with a first contact amount in a first span in a longitudinal direction of the heater, where the contact member contacts the fixing belt. The heater contacts the holder with a second contact amount, that is greater than the first contact amount, in a second span in the longitudinal direction of the heater, where the contact member does not contact the fixing belt.
