<p>In order that the air surrounding a fixing member is prevented from entering a blowing section for blowing separation air, a wind speed setting section 3ba is provided with switchable control modes, namely, a first control mode (control mode for operating the blower fan 57 at a wind speed for separation) and a second control mode (control mode for operating the blower fan 57 at a low speed). This structure allows the blower fan 57 to be controlled in conformity to any one of these first and second control modes.
