摘要： PROBLEM TO BE SOLVED: To prevent exposure means from becoming stained by toner floating on an image carrier side.SOLUTION: An air flow B2 generated from a fresh air supply port 35C of a second air intake duct 35 that is disposed on a left upper rear face of an image forming apparatus 1 flows into a clearance between a cover 17C and an exposure casing 17B and joins an air flow A2 generated from a fresh air supply port 30B of a first air intake duct 30, and then, flows toward a drum-cartridge 10 from a clearance between exposure casings 17A and 17B. A positive pressure is generated between the cover 17C and the exposure casings 17A and 17B by the air flows A2 and B2 joined together. The positive pressure generated on an exposure device 16 side prevents the air on the drum-cartridge 10 side from ascending to the exposure device 16 side.
