Abstract
A fixing device includes a film-shaped cylinder, a heater unit, and a guide portion. The heater unit is disposed inside the cylinder and includes a heating element. The guide portion can contact an inner surface of the cylinder. A standard size sheet having a maximum width among standard size sheets that are conveyed together with rotation of the cylinder while being in contact with an outer surface of the cylinder is set as a maximum standard size sheet. A position corresponding to a center portion of the maximum standard size sheet is set as a first position. A position corresponding to an end portion of the maximum standard size sheet is set as a second position. In the guide portion, a contact length with the cylinder at the second position is shorter than a contact length with the cylinder at the first position.
