1. An image forming apparatus, comprising:
a main body casing; a drum unit including a photoconductive drum having a central axis extending in a first direction, and a charging device configured to charge the photoconductive drum; a fixing unit arranged adjacent to the drum unit and configured to fix an image on a printing medium; a fan configured to generate an air flow inside the main body casing; a filter configured to remove ozone included in the air passing therethrough; a first channel defined in the main body casing, the air directed from the fixing unit toward the fan flowing in the first channel; a second channel defined in the main body casing, the air directed from the charging device toward the fan flowing in the second channel, the filter being provided in the second channel, the second channel being arranged next to the first channel; and a blocking member configured to block communication between the first channel and the second channel, one end of the blocking member is fixed to a portion of the main body casing on a downstream side, in a feeding direction of the printing medium, with respect to the drum unit, and on an upstream side with respect to the fixing unit, while the other end of the blocking member contacts the drum unit, wherein the one end of the blocking member and the other end of the blocking member are arranged on a same side with respect to a sheet conveying path.
