Toner Business

What is toner?

Toner refers to the powdered printing ink used in copiers, laser printers, FAX machines and multi-function printers (MFP).
In copiers and laser printers alike, toner is the only material that must contact the many components during image development. Thus, the attributes required of toner for printing are quite important. It is for this reason that high-quality toner is indispensable for accurately reproducing data as visual images.

The Relationship between our Toner Business and the Market

In recent years, the cartridge recycling market has shown a trend for worldwide growth. Our toner is used all over the world to refill used cartridges, and as of 2006, we ranked 7th in the world in terms of toner production. IMEX is the only venture corporation in the top ten toner companies in the world.

Toner Production Process

Toners are used in copying machines and laser printers that employ electrophotography. As printers become capable of printing faster and finer images, toners as well are required to provide higher printing quality and color reproduction.
IMEX’s toner has promptly met those requirements in the industry and is used widely throughout the world. With the venture firm’s resolve to meet toner requirements swiftly as its strength, IMEX is ranked among the world’s top ten toner manufacturers.

(1)Raw Material Mixing
Raw materials such as resin, magnetite, carbon (or pigment), CCA and WAX are mixed in a high-speed mixer.
(2)Compounding
The raw materials above are kneaded in a mixer and reduced to a manageable size.
(3)Pulverizing
The mixture that has been coarsely reduced is pulverized to about 6~10μm. (1μm = 1/1,000mm)
(4)Classifying
Large and small particles are sorted out from the pulverized particles and only those particles of the necessary size are sent to the next step.
(5)Post Additive Blending
6~10μm toner extracted during the sorting process is coated with a nano (n) sized adhesive. (1nm = 1/1,000,000mm)
(6)Sieving
Clumped matter is removed using a vibrating sieve.
(7)Completion
The product is complete.
