Abstract
PURPOSE:To improve toner capturing ability by forming a filter bag for containing the toner having been cleaned to a these layer consitution provided with specified vent holes and making use of the air current by a suction fan. CONSTITUTION:A filter bag 15 is formed in multilayer tripple wall construction comprising an outer wall body 20 formed of a non-woven fabric, an intermediate wall body 21 provided with 40 to 500 pieces/cm<3> of vent holes and an inner wall body 22 provided with 2 to 40 pieces/cm<3> of vent holes. Hence, the excess toner having been removed from a photosensitive drum 10 by a fur brush 13 is well contained in the bag 15 unit it is filled by the suction air current by a suction fan 19. As a result of this, the toner capturing ability of the filter bag increases, the life of bag prolonges and its maintenance and inspection are simplified.
