PURPOSE:To facilitate the recycling of a charged residual toner to save space and efficiently remove the paper dust of the residual toner while avoiding increase in number of parts as much as possible by providing such a constitution as capable of recovering only the charged paper dust by utilizing static electricity while magnetically holding the charged residual toner. CONSTITUTION:The toner including paper dust guided to the bottom part of a carrying mechanism 21 is charged to plus by a first charger 51, and carried to a frame body opening 26 provided in the course of inclination by rotating a belt 21 by the rotation of a driving pulley connected to a screw shaft end and utilizing the partitioning wall 25 of the belt 21. In the frame body opening 26, only the magnetic residual toner is carried on a discharge hole side as it is in the state where it is magnetically attracted by the belt 21, while the paper dust receives the minus charging force of a second charger 53, and is separated from the residual toner and fallen on a recovering part 52 side below. |
