Dry ink (toner) is a very promising industry. With an increase in sales based on a survey as much as 42% every years. This figure is predicted to continue to increase along with the development of printing technology using toner and the possibility to make a new formula from toner. The formula for the toner maker consists of a polymer, a colorant and a control agent. Control agents are generally used to activate the magnetic characteristics of toner the material contains is a magnetic mineral. In this study, characterization was carried out to identify magnetic minerals used as control agents for activating magnetic characteristics such as amount, composition, phase of magnetic minerals. The toner used is TN2356, SM, P115, P1102, H85, CP1028. With the susceptibility method using the Bartington Magnetic Susceptibility MS2B tool, the susceptibility values of each TN2356 (9,50 x 10-8 m3/kg) SM (514,03 x 10-8 m3/kg) P115 (46,17 x 10-8 m3/kg) CP1028 (566,80 x 10-8 m3/kg) H85 (21153,47 x 10-8 m3/kg) P1102 (21194,77 x 10-8 m3/kg). Composition of toner using X-Ray Fluorescence (Fe,Ti,Ce,Si,P). The phase used by X-Ray Diffraction is magnetite (Fe3O4),except 2 samples contain magnetic minerals but dominantly contain Cerium Oxide (CeO2) phase P115 and TN2356. © Published under licence by IOP Publishing Ltd.
