Heat fixing device

Abstract

Abstract PURPOSE:To uniformly and efficiently cool the inside temp. of a heat fixing device by mounting a discharge fan and suction fan to the periphery of the fixing rollers of the heat fixing device. CONSTITUTION:The discharge fan and the suction fan are mounted to the periphery of the fixing rollers of the heat fixing device of a printer or copying machine for which an electrophotographic process is used. For example, the suction fan 12 is installed coaxially with the discharge fan 11 to the periphery of the fixing rollers. The heat generated from the fixing rollers is thereby forcibly blasted by the suction fan to the discharge fan side and is discharged by the discharge fan, by which the inside temp. of the heat fixing device is uniformly and efficiently cooled.
