Abstract
An inside contamination preventing mechanism is provided that is adapted to be positioned in an imaging apparatus utilizing an electrophotographic system for forming an image on a predetermined recording medium and having an air directing mechanism including an air intake portion through which air flows from the outside of the imaging apparatus and a driving member for driving the air to a predetermined portion through a predetermined area within the imaging apparatus, and a toner containing member that is located adjacent to the air intake portion for containing the toner particles remaining in the imaging apparatus after an imaging operation onto the predetermined recording medium. The inside contamination preventing mechanism includes a cover member provided on an inner surface of the imaging apparatus for covering an opening of the toner containing member. Thus, it becomes possible to prevent the toner from floating in the air, and accordingly, it becomes possible to keep the inside of the imaging apparatus clean.
