A sheet cooling apparatus includes: a fixing device that fixes a toner image on a sheet; an ejection section that ejects the sheet on which the toner image has been fixed; a stacking section that stacks the sheet ejected by the ejection section; an air blowing device that blows air; a first air blowing path that guides the air from the air blowing device so that the air passes through the ejection section; and a second air blowing path that guides the air so as to suppress inflow of the air into the stacking section in a state where the first air blowing path is blocked by the sheet ejected by the ejection section.
