A board marker eraser is provided to prevent the contamination of atmosphere due to the falling of dust. A board marker eraser comprises a dust tub(100) which accumulates and stores dust in the internal space; a dust tub cover(200) which opens and closes the upper surface of the dust tub; a belt-type eraser sheet(300) which erases the letter on a board; a roller(400) which is surrounded with the eraser sheet and is mounted to the both terminal lower parts inside the dust tub so as to rotate; a roller handle(500) which is mounted to the roller so as to rotate the roller; and a dust separation brush(700) which collects the dust adhered to the surface of the eraser sheet to separate it.
