PURPOSE:To easily discriminate waste toners and to recover a drum base body for the purpose of reuse as a drum base body or as resources by incorporating a housing bag for housing the waste toners into the drum base body. CONSTITUTION:The housing bag 2 is incorporated into the drum base body 1 and a flange 3 having an aperture 4 for transporting the waste toners is mounted at one end of the drum base body 1. A flange 5 which is mounted with a core shaft 6 and is not provided with the aperture is mounted to the other end. The housing bag 2 is joined in tight contact with the aperture 4 of the flange 3 in such a manner that the waste toners do not leak to the outside. The toners removed from the surface of the cleaned photosensitive drum are housed into the housing bag 2 mounted within the drum base body 1 by a suitable means. The housing bag 2 is removed from the drum base body 1 when the life of the photosensitive drum runs out or the housing bag 2 is filled full. The drum base body 1 from which the housing bag 2 is removed is recovered for reuse as the drum base body or as resources. |
