Between a cleaner frame and a reinforced frame of an image forming unit, a junction duct is formed to flow a airflow from a inlet port to a exhaust port of a main body of an apparatus, a space between a fixing unit and the image forming unit is blocked by the airflow, heating of the image forming unit by radiant heat of a fixing unit is prevented, and by blocking a space between the image forming unit and the image quality is improved and the recycle use of recovered toner is realized.
