ABSTRACT:
An object of the invention is to prevent a silicone gas generated in a fixing unit from entering into a charger. A corona wind rises when the charger corona-discharges, and air is taken in through an outside-air intake. The air flows in through the air passage and the air inlet and flows out through a front opening as an air flow. The silicone gas is isolated by the airflow and prevented from entering into the charger.
