An image forming apparatus includes an image forming unit configured to form a toner image on a recording material, a fixing unit configured to fix the toner image on the recording material by heat, a cooling air generating unit configured to generate a cooling air, and an air supplying unit configured to supply the cooling air toward the image forming unit. In addition, a primary water absorbing portion is configured to absorb water generated by the cooling air generating unit, and a secondary water absorbing portion is disposed at a position lower than the primary water absorbing portion in a gravitational direction and configured to absorb the water supplied through the primary water absorbing portion. An air blowing unit blows air warmed by the fixing unit toward the primary and secondary water absorbing portions to evaporate the water absorbed in the first and secondary water absorbing portions.
