Abstract
A fixing device includes: a tubular member having an outer peripheral surface, an inner peripheral surface defining an internal space, and an axis defining an axial direction, the tubular member being configured to move around the axis; a heater disposed in an internal space to radiate heat; a nip member that contacts the inner peripheral surface to transmit the heat to the tubular member; a backup member that is in contact with the outer peripheral surface to form a nip region between the backup member and the tubular member, the backup member applying a load to the nip member; and a stay disposed in the internal space to support the nip member against the load. The nip member includes: a first member that contacts the inner peripheral surface; and a second member disposed between the first member and the stay to transmit the load to the stay.
