ABSTRACT:
In an image forming apparatus that uses a charging unit to charge a photosensitive drum, forms an electrostatic latent image by carrying out image exposure according to image information, and transfers to a paper the electrostatic latent image by developing the electrostatic latent image into a visible image using a developer so that the image information is presented, an exhaust duct33for exhausting air that contains ozone produced within a drum unit30, which includes a photosensitive drum3and a charging unit5, and a duct32for taking in air, which draws in fresh air, are provided within the drum unit30so that ventilation of the drum unit30can be carried out with excellent efficiency.
