範囲第１項に記載の装置。[Scope of Claim for Utility Model Registration] 1. A toner collection box body that is box-shaped and has an opening on its top wall, and a bag-shaped toner collection box body that is housed within the toner collection box body and whose bag opening is located on the top surface of the toner collection box body. A toner collection bag that is closely attached to an opening in a wall and receives the toner collected by a cleaning device, and a bottom wall of this bag that deforms the part where the toner falls by directly or indirectly applying wind pressure from below to collect the toner. A toner collection device equipped with a wind pressure supply means capable of flattening toner piled up in a collection bag. 2. The wind pressure supply means includes a through hole formed in the bottom wall of the toner collection box body facing the toner falling portion of the toner collection bag body, a fan, a passage leading from the high pressure side of the fan to the through hole, and A closing plate is attached to the passage and releasably closes the passage, and the closing plate is opened, thereby applying wind pressure to the toner falling portion of the toner collection bag through the passage and the through hole to deform it, and removing the toner. 2. The apparatus according to claim 1, further comprising a closing plate actuating means capable of flattening a mountain of toner accumulated inside the collection bag.
