Abstract
A fixing device includes a rotator, a pressure member, a conductor, and a heater. The pressing member presses the rotator to form a nip between the rotator and the pressing member. The conductor is grounded and includes a contact portion having a limiting shape to limit a contact area in which the contact portion is in contact with an inner circumferential surface of the rotator. The heater is in contact with the inner circumferential surface of the rotator to heat the rotator.
