Abstract
A fixing device includes first and second rotation members, a heater holder having a protrusion, and a heater having a heating element and a substrate having a longitudinal direction and a thickness direction. The protrusion is disposed at a position, which is outside a nip portion and on a downstream side in a conveyance direction of a recording material, and comes into contact with the first rotation member. The protrusion protrudes in the thickness direction toward the second rotation member without crossing a nip tangent line that passes through a contact surface between the first rotation member and the second rotation member and extends parallel to the contact surface, and a length in the longitudinal direction of the protrusion is shorter than a length in the longitudinal direction of the recording material of a maximum size which is able to be conveyed.
