An image forming apparatus includes an image forming unit that forms an image when a working state of the image forming unit is an image forming state and does not form an image when the working state is a non-image forming state, an air blowing part that blows air toward the image forming unit, an air flow rate changing part that changes a flow rate of the air blown toward the image forming unit from the air blowing part, and a switching part that performs a switching to switch the working state of the image forming unit between the image forming state and a non-image forming state, wherein the air flow rate changing part changes the air flow rate of the air blowing part in mechanical correspondence with the switching between the image forming state and the non-image forming state of the image forming unit by the switching part.
