A cartridge includes a first chamber provided with a discharge opening; a filter; a second chamber provided with an inlet for taking in the air from an outside of the cartridge; a pipe provided in the first chamber and for permitting passing of the toner, wherein the pipe is provided with a first pipe opening and a second pipe opening for communicating with the discharge opening, the pipe being extended from the first pipe opening to the second pipe opening; and a memory. In a case where a direction in which the first chamber and the second chamber are arranged is a gravitational direction and the cartridge is directed in a predetermined direction in which at least a part of the first chamber is positioned above the second chamber, the memory is provided on an upper surface or a lower surface of the cartridge.

A toner container for use in an image forming device includes a housing having a reservoir for storing toner, a paddle positioned within the reservoir, and a rotatable drive member positioned to push the paddle in a first rotational direction. The paddle is free to rotate ahead of the drive member in the first rotational direction. A magnet is rotatably coupled to one of the paddle and the drive member. A shield is rotatably coupled to the other of the paddle and the drive member such that the shield is movable between a blocking position for attenuating a 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 paddle relative to the drive member.

An image forming apparatus includes a rotary which is rotatable and to which a cartridge is detachably attached, a drive source, a transmission device, a moving device configured to be driven by driving force of the drive source transmitted via the transmission device to move the cartridge, the moving device including a driven portion that is provided in the rotary and is configured to receive the driving force from the transmission device, and a locking mechanism capable of taking a locking state in which the locking mechanism restricts a rotation of the rotary and a lock releasing state in which the locking mechanism allows the rotation of the rotary, the locking mechanism being configured to take the locking state in a state in which the rotary is in the replacement posture.
