Claim:
An image forming apparatus comprising: an image forming unit configured to form a toner image on a sheet; a fixing unit configured to fix the toner image on the sheet by heat; a conveying path in which the sheet on which the toner image was fixed by the fixing unit passes, wherein the conveying path diverges in a first direction and a second direction at a diverging portion and has a first conveying path in which a sheet conveyed in the first direction passes and a second conveying path in which a sheet conveyed in the second direction passes; a cooling fan configured to supply air into the first conveying path so as to cool the sheet in the first conveying path; a movable guiding member provided on the diverging portion for guiding a sheet, wherein the guiding member moves between a first position for guiding a sheet to the first conveying path and a second position for guiding a sheet to the second conveying path wherein the guiding member can prevent the air which has been supplied into the first conveying path by the cooling fan from flowing into the fixing unit by way of the conveying path.
