FLUORESCENT MAGNETIC POWDER, METHOD FOR PRODUCING THE SAME, MAGNETIC INK COMPOSITION, MAGNETIC POLYMER PARTICLES, LIQUID DEVELOPER FOR MAGNETIC LATENT IMAGE, CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a fluorescent magnetic powder having high hiding property with fluorescence and a high degree of freedom of application media and suitably usable for a color display material and a printing material, a method for producing the powder, a color toner giving a good color image and color display, a magnetic ink composition suitably usable for a color display, etc., magnetic polymer particles, a liquid developer for a magnetic latent image, a cartridge and an image forming apparatus. PSOLUTION: In the fluorescent magnetic powder, a fluorescent dye is fixed on a surface of magnetic powder. Alternatively, in the fluorescent magnetic powder, a resin layer having a functional group is provided to a surface of magnetic powder and the fluorescent dye reacts with the functional group and is attached to the resin layer.
