Abstract
A fixing device includes a fixing member, a housing, and heating-side and pressing-side heat conservation plates. The fixing member includes a heating member and a pressing member that is in pressure contact with the heating member. The housing includes the fixing member and has openings on upstream and downstream sides in a recording medium transportation direction. The heating-side heat conservation plate opposes the heating member so as to be spaced apart from an outer peripheral surface of the heating member. The pressing-side heat conservation plate opposes the pressing member so as to be spaced apart from an outer peripheral surface of the pressing member. A distance between the pressing member and the pressing-side heat conservation plate is greater than a distance between the heating member and the heating-side heat conservation plate.
