There is provided an image forming apparatus which effectively suppresses an increase in temperature of a heating means by an air blowing means when image formation is performed to a small-size recording material and can continuously perform the image formation even though the air blowing means. The image forming apparatus includes a heating means to heat a recording material to be conveyed, a cooling fan which blows air from an air blowing port facing a part of the heating means, a shutter which moves such that an opening width of the air blowing ports is regulated depending on a width of the recording material, and an error detecting means which detects an error of the cooling fan. When the error detecting means detects an error of the cooling fan, the shutter moves to such a position that the cooling fan in which an error is detected, so that image formation is continued.
