PURPOSE:To obtain an encapsulated magnetic toner having a sharp color by covering a core material with a shell material obtained by dispersing an inorganic powder into a polymer. CONSTITUTION:The magnetic toner having a sharp color can be obtained by covering the core material 1 having the color of the magnetic particles and hiding said color with the shell material layer 2 prepared by dispersing into the polymer the inorganic powder, such as powders of aluminum, nickel, silver, titanium dioxide, aluminum oxide, zinc sulfide, lead titanate, zirconium oxide, white lead, zinc white, minium, cadmium red, or cadmium yellow, and the color of the magnetic particles of the core material can be effectively hidden by using the inorganic powder having a refractive index of >=1.9. |
