Toner contains multiple additives for expression of various functions. Toner is designed and manufactured by arranging these additives to ensure the most effective expression of relevant functions. Therefore, to manufacture toner according to its design, it is important to understand the actual shape of toner particles produced and internal conditions thereof. To examine internal structures having a particular particle size, toner particles of 4-6 μm were analyzed by ultra-high voltage electron microscope (UHVEM) tomography. Tomographic analysis provided complete information about three-dimensional distribution of wax and pigments. Furthermore, this method showed the presence of charge control agent over the toner surface.
