Abstract
The present invention prevents condensation on a pressure roller and excessive temperature rise of a non-paper-passage portion of a fixing unit by switching a blower unit that cools the fixing unit between a blowing mode in which the blower unit sends air to the non-paper-passage portion and an exhausting mode in which a fan of the blower unit is rotated reversely and the air in the fixing unit is exhausted out of the apparatus.
