An image forming apparatus (1) includes an image forming section(300), a housing (10), an image scanning section (3B), an airflow generation section(12Lb), a guiding air path (126), and a blow-off port (125). The image forming section (300) forms an image on a sheet. The housing (10) accommodates the image forming section (300) therein. The image scanning section (300) has a bottom portion (35) and is disposed above the housing (10). The airflow generation section (12Lb) generates an airflow inside the housing (10). The guiding air path (126) guides the airflow upward inside the housing (10). The blow-off port (125) is communicated with the guiding air path (126) and arranged so as to face the bottom portion (35) of the image scanning section (300).
