A toner transportation device includes a toner containing case and a drive section. The toner containing case includes a case main body containing toner, and an agitating unit rotatably provided in the case main body and agitates the toner. The drive section includes a driving unit driving the agitating unit, a detection unit detecting a driving unit driving state, and a control unit able to transmit a drive instruction signal to the driving unit and receive a detection signal regarding the driving unit driving state from the detection unit. The control unit determines whether the toner containing case is in an overload state in accordance with a detection signal reception state. The control unit performs retry control, which causes the driving unit to repeatedly rotate the agitating unit in forward and reverse rotation directions when the control unit determines that the toner containing case is in the overload state. |
