PURPOSE:To prevent air blasting sound and micro dust due to air blasting from being emitted at the time of cooling an exoergic source by collecting heat being generated from plural exoergic sources in an image forming device on a saturated vapor cooling part, and cooling it by an electronic cooling device. CONSTITUTION:The heat in the exoergic sources (25-27) in the image forming device 21 is absorbed by the vaporization of heating medium liquid in heat pipes (31-34) arranged in the neighborhood of the exoergic source, and is radiated by the liquefaction of the saturated vapor of the heating medium liquid in the saturated vapor cooling part 37. The heat radiated at the saturated vapor cooling part 37 is cooled by the electronic cooling device 38 arranged at the saturated vapor cooling part 37. In such a way, it is possible to cool the exoergic sources (25-28) in the image formation device 21 without using a fan for cooling, and to prevent the air blasting sound of the fan and the micro dust due to the air blasting from being emitted. |
