PURPOSE:To prevent overflow by arranging a toner feeding tank magnetically carrying magnetic toner in the longitudinal direction so that the recovered magnetic toner is combined with unused magnetic toner in the feeding tank. CONSTITUTION:A toner carrying roll 83 obtained by pivoting a permanent magnetic roll 82 in an inner cylinder type non-magnetic sleeve 81 is arranged on the lower part of the toner feeding tank 8 for storing spare magnetic toner. A seal part 8'' contacted with an opening part 8' and the non-magnetic sleeve 81 is formed between the carrying roll 83 and the toner feeding tank 8 so that unused feed from the cartridge is combined with rotating toner from a cleaner, so that the recovery toner from the cleaner is carried and fed with priority. Thus, the feeding tank is prevented from overflow state due to the recovery toner. |
