Abstract
Provided is a toner transport mechanism including: a first movable member which is displaced in accordance with an amount of toner in a transport path for transporting toner; a second movable member which is displaced in accordance with a rotation of a transporting member provided in the transport path; and a flag member which is displaced to an acting position where the flag member acts on a sensor and a non-acting position where the flag member does not act on the sensor, in accordance with the displacement of the first movable member and the displacement of the second movable member, the sensor being arranged outside of a duct and detecting an anomaly of the toner transport mechanism.
Claims2
