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.
Copier/printer
Product features
- Able to control electrical characteristics (resistivity), magnetic characteristics (magnetizing force), and physical characteristics (specific gravity and particle size distribution).
- Supports magnetite type, Mn type, and MnMg type as the product compositions.
- Able to supply resin coated products.
