摘要： An image forming apparatus includes: a charging section configured to charge a surface of an image bearing member; an air-intake duct having an air-supply port, and configured to guide air sucked from an outside to the charging section through the air-supply port; an exhaust duct having an air-intake port, and configured to suck air around the charging section through the air-intake port and eject the air thus sucked. The air-intake duct has a configuration in which air guided to the charging section through the air-supply port flows in a direction orthogonal to a longitudinal direction of the charging section, or flows toward a center of the charging section in the longitudinal direction.
