TEM observation of Toners



A toner for a laser printer and a copy machine normally consists of several kinds of materials like a resin, a coloring material, Carbon Black(CB), Wax etc. It is important for a toner manufacturer to control the amount and dispersion of additives to achieve good quality of a toner.

ANAC can provide customers with a clear TEM image of such a toner through our unique pretreatment process. You can see clear dispersion state of Wax, CB, TiO2 etc. on a toner particle
