Carrier powder

Carrier Powder

Carrier powder is spherical soft ferrite that is used in electro-photo printers such as copiers.

High speed, high picture quality, and high durability that are required of carrier powder for electro-photo printers are realized by controlling the electrical characteristics (resistivity), magnetic characteristics (magnetizing force), and physical characteristics (specific gravity and particle size distribution).

Applications

This is a magnetic material that plays a part in carrying toner inside a copier.
Carrier powder is used inside a copier that uses toner.
