Toner container having a magnet for toner level sensing

A toner container for use in an image forming device, comprising:

• a housing having a reservoir for storing toner;
• a first rotatable member positioned in the reservoir;
• a second rotatable member positioned to push the first rotatable in a first rotational direction, the first rotatable member is free to rotate ahead of the second rotatable member in the first rotational direction;
• a magnet having a magnetic field, the magnet is rotatably coupled to one of the first rotatable member and the second rotatable member;
• and
• a shield rotatably coupled to the other of the first rotatable member and the second rotatable member such that the shield is movable between a blocking position for attenuating the magnetic field of the magnet to block detection of the magnetic field by a magnetic sensor and an unblocking position for unblocking the magnetic field of the magnet to permit detection of the magnetic field by the magnetic sensor based on a rotational position of the first rotatable member relative to the second rotatable member.
