Abstract

PURPOSE:To prevent the inside of the copying machine and the transcription material from becoming dirty, by constituting a passage up to the transfer member by the guide member provided on the lower part of the scoop member, and providing a rotatable magnetic means which goes across this passage and absorbs a developing agent. CONSTITUTION:The supporting part 16 is located under the cleaning blade 12, and a sheet-form scoop member 13 is installed on the supporting part 16. The scoop member 13 is selected so that the length and relative angle for making its end part contact with the drum surface 111 can have an optimal effect on scooping a toner. The lower tip of the outside frame of the body 14 extends downwards from the supporting part 16, the guide member 17 is formed, and the passage of a toner, which has passed through up to the screw 15 is constituted of the scoop member 13 and the guide member 17. In addition, is provided a rotatable magnet roller 20 which is arranged so that it goes across the passage at the rear of this passage 18, and absorbs a toner coming into this passage. In this way, it is possible to prevent the inside of the copying machine and the transcription material from becoming dirty due to a dropped toner.
