When the toner bottle is set, the transport nozzle on the side of the unit is inserted into the bottle (Hi-Act system).
When the piezoelectric sensor in the sub-hopper detects there is no toner, the toner bottle drive motor (M11) (M12) (M13) (M14) rotates. The rotation of the toner bottle drive motor (M11) (M12) (M13) (M14) is transmitted to a transport coil via a drive gear, and toner in the bottle is transported horizontally. Due to the coil transport, stable toner supply/enhanced supply precision/reduction of residual toner are achieved.

Toner transported by the coil falls directly into the sub-hopper via the transport pipe.
To prevent toner from remaining, the rocking spring [A] in the transport pipe moves up and down together with the coil.
