Abstract
A fixing device includes a heating rotary body, a pressure rotary body, a heater, and a thermal conductive member. The pressure rotary body is configured to form a nipping portion and to convey a sheet in a conveying direction while nipping the sheet between the pressure rotary body and the heating rotary body. The heater includes a substrate having a first surface and a second surface, and a first and second resistance heating elements provided on the first surface. The first and second resistance heating elements extend in a crossing direction crossing the conveying direction and are positioned apart from each other by a predetermined distance in the conveying direction. The thermal conductive member is in contact with the second surface. In the conveying direction, the thermal conductive member has a dimension greater than the predetermined distance and smaller than or equal to a dimension of the nipping portion.
