Abstract

PURPOSE:To make the replacing time of an air filter clear, and to perform invariably excellent fixation, by detecting the air suction pressure of the sucking source of the air filter, and giving an alarm when the pressure drops. CONSTITUTION:The suction intake 15 of the discharging air duct of a fixing device is positioned on the outlet side of a lamp house, and the other end is connected to a discharging blower 17. A pressure switch 18 and an alarm display unit 19 are provided between an air filter 16 and the blower 17. When the filter 16 chokes up, the internal pressure of the suction duct of the blower 17 drops and the pressure drop is detected by the pressur switch 18 to perform prescribed display on the display unit 19 while an alarm is given. Therefore, the silting of the filter 16 is made clear to perform invariably excellent fixation.
