A fixing device includes a fixing rotator that is flexible, endless, and rotatable. A heater heats the fixing rotator. A pressure rotator is disposed opposite the fixing rotator. A nip former defines a fixing nip between the fixing rotator and the pressure rotator. A support supports the nip former. The nip former includes a back face that contacts the support and has a nonlinear shape in a longitudinal direction of the nip former.
