Imaging forming apparatus with improved exhaust flow

摘要

An image forming apparatus having improved air flow and/or handling of toner or other debris between a fixing device and an image carrier. In accordance with one aspect of the invention, the completeness and effectiveness of an air exhaust system of an image forming apparatus is improved by utilizing a flow improvement board which is located between the image carrier and the fixing device. The flow improvement board can be mounted upon the fixing device and extends downwardly beyond the fixing device. The flow improvement board provides a more regular flow of air toward the exhaust device thereby improving the effectiveness and completeness of the exhaustion of air. In addition, in accordance with another aspect of the invention, a magnet can be provided upon the board or associated with the fixing device, with the magnet including a plurality of poles which alternately extend along the widthwise direction of the mixing device. The magnet removes floating toner, and is oriented for most effective results with the flow produced by the flow improvement board.
