Abstract

An insertion passage 104 Y for inserting a suction nozzle 73 Y fixed to an image forming apparatus is provided on a holder 102 Y, and a connecting passage 114 Y that connects the insertion passage 104 Y and a toner storage section 106 Y of the holder 102 Y is provided. After the toner sent from bottle 101 Y to the holder 102 Y falls towards the connecting passage 104 Y, the toner flows into the suction nozzle 73 Y through the connecting passage 114 Y and is then discharged out of the holder 102 Y. An airtightness between the insertion passage 114 Y and the suction nozzle 73 Y inserted into the insertion passage 114 Y is superior than an airtightness between the bottle 101 Y and the holder 102 Y engaged with the bottle 101 Y.
