摘要： A fixing device includes a rotatable heating member including a heat source and a pressure-applying member pressed against the heating member. The pressure-applying member includes a band-shaped member that extends in a width direction of a medium that passes through a fixing area, a support member opposed to the heating member with the band-shaped member disposed therebetween, and a pressing member including a base-end portion supported by the support member and a free-end portion that extends toward the fixing area. The pressing member has urging portions arranged with intervals therebetween in the width direction. The urging portions are elastically deformable in accordance with a thickness of the medium when the medium passes through the fixing area. The free-end portion urges the band-shaped member toward the heating member so that the band-shaped member is pressed against the heating member.
