Abstract

PURPOSE: To make it possible to produce by a relatively simple method the toner material, which contains no air pollutant and which has its fixing property improved, by coating the liquid droplets containing a color agent with a group of hydrophobic organic substance particles.
CONSTITUTION: A watersoluble dye or an agueous dispersion of pigment is dissolved or dispersed in a water medium. To the aqueous solution or dispersion thus obtained, a hydrophobic organic substance particles having a diamerter of 5 to 50 mμ such as calcium stearate are added. A high shearing force is applied to the resultant mixture in an apparatus such as a waring blender so that the respective droplets having a desired color agent are produced and are instantly coated with the hydrophobic organic substance particles under a discontinuous layer. Those droplets may contain a fixation promoting agent such as a magnetic material or glycerin. Moreover, it is preferred that 12 to 125 wt. parts of the droplets are mixed with 100 wt. parts of the hydrophobic organic substance particles.
