Abstract:
1. A fixing device comprising: a heat unit that heats a toner image on a first recording medium; and a heat absorption and transmission unit that absorbs heat of the first recording medium sent from the heat unit and transmits the heat thus absorbed to a second recording medium to be sent to the heat unit, wherein the heat absorption and transmission unit comprises a belt member which is stretched over and circulated around a plurality of tensile members to transport the first and second recording media, the belt member having a heat absorption portion downstream from the heat unit and a heat transmission portion upstream from the heat unit, wherein the heat absorption portion contacts the first recording medium and absorbs heat from the first recording medium in a state that periphery of a contact region between the belt member and the first recording medium and transmits heat to the second recording medium in a state that a periphery of a contact region between the belt member and the second recording medium is thermally insulated, and wherein the belt member is disposed to pass through a heating portion of the heat unit.
