An image forming apparatus includes an apparatus main body and a drum unit. The apparatus main body has an opening and a drum unit storage part communicating with the opening. The drum unit is detachably attached to the drum unit storage part through the opening. The drum unit includes photosensitive drum, a corona discharging device and a drum cover. The corona discharging device corona-charges the photosensitive drum. The drum cover is turnable in a protective posture for covering the photosensitive drum and an exposure posture for exposing the photosensitive drum. When the drum unit is attached to the drum unit storage part, the drum cover is turned from the protective posture into the expose posture to block a flow path communicating a space around the corona charging device with an outside of the apparatus main body.
