Abstract
A waste toner detection mechanism includes a transmission member and a flag member. The transmission member transmits the rotation of a rotation transmission member to a stirring shaft. The transmission member can move between the farthest position and the closest position to the rotation transmission member in the axial direction of the stirring shaft and moves from the farthest position to the closest position with an increase in difference in rotation between the rotation transmission member and the stirring shaft. The transmission member has a locking portion elastically engaged with the rotation transmission member in the closest position and restricts movement of the transmission member to the farthest position. The flag member moves from a retracting position of being stored in the waste toner container to an exposing position of being exposed from the waste toner container with the transmission member moving from the farthest position to the closest position.
