Controlling supply of magnetic material

An apparatus for providing a developer, the apparatus comprising:

• a first container to contain a volume of a magnetic carrier;
• a second container to contain a volume of a developer;
• a connecting member having a first end coupled to the reservoir and a second end opposite to the first end, the connecting member to transfer the magnetic carrier from the first container to the second container;
• and
• a magnet movable in relation to the connecting member,
• wherein, a magnetic field produced by the magnet controls the transfer of the magnetic carrier through the connecting member.

An image forming apparatus comprising:

• a reservoir to contain a magnetic carrier;
• a developer cartridge to contain a developer;
• a connecting member having a first end coupled to the reservoir to receive the magnetic carrier and a second end, opposite to the first end, coupled to developer cartridge, the connecting member to transfer the magnetic carrier from the reservoir to the developer cartridge;
• a magnet movable in relation to the connecting member;
• and
• a magnet controller, coupled to the magnet, to control the movement of the magnet in relation to the connecting member,
• wherein, a magnetic field produced by the magnet controls movement of the magnetic carrier through the connecting member.
