Abstract
A toner transportation device includes a toner case and a drive section. The toner case includes a main body containing toner, and an agitating unit rotatably mounted in the main body that 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 case is in an overload state in accordance with a detection signal reception state. The control unit performs a retry control, causing the driving unit to repeatedly rotate the agitating unit forward and backward when the control unit determines that the toner case is in an overload state.
