PROBLEM TO BE SOLVED: To provide an image forming device which suppresses increase in the temperature of a photoreceptor, cools the photoreceptor, prevents production of abnormal images, reduces the space and the cost by using the inside of the photoreceptor for the treatment of ozone. SOLUTION: The external air introduced by a sucking fan 23 passes through a sucking duct 24, the casing 9 of an electrification charger 6 and an aperture 11 to reach the surface of a photoreceptor drum 2 to flow in the case of a photoreceptor unit 20 and passes through the entrance aperture 29 formed in a flange member 4 of the photoreceptor drum 2 into the inside of the photoreceptor drum 2. Then the air passes through the exit aperture 28 formed in the flange member 3 by the operation of a discharge fan 31, through the discharge port 35 formed in the rear part of the case of the photoreceptor unit 20 and through a discharge duct 32 to be discharged to the outside of the image forming device. |
