PURPOSE:To send in a scattered toner efficiently and to maintain toner attracting force by providing a cylindrical brush which rotates in the same direction with a photosensitive body to a duct entrance arranged nearby a developing device, etc., provided adjacently to the phososensitive body. CONSTITUTION:The cylindrical brush 7 is provided to the duct entrance 4 and the cylindrical brush 7 is rotated by a driving system which is not shown in a figure in the same direction with the photosensitive body 1 to send the scattered toner into the duct entrance 4 efficiently. Thus, the duct entrance 4 is cleaned at any time to maintain the toner attracting force and eliminate deterioration in picture quality. The cylindrical brush is formed by flocking fibers in a cylindrical core and fiber 9 is flocked in a paper pipe 8. The fiber 9 uses conductive fibers obtained by dispersing a conductor of carbon, etc., in fiber or artificial fiber of acryl, nylon, rayon, etc., of a plated fiber brush, metallic brush, and artificial fiber brush. |
