摘要：
A toner transportation device includes a toner case and a drive section. The toner case includes a main body that contains toner, a discharge port located in the main body and allowing toner to pass therethrough, and a transportation unit rotatably positioned in the main body for transporting the toner toward the discharge port. The drive section includes a driving unit that drives the transportation unit, a detection unit that detects rotation of the transportation unit and outputs a rotation number detection signal, and a control unit that estimates an amount of toner remaining in the toner case based on an accumulated number of times the rotation number detection signal has been outputted from the detection unit.
