<p>PURPOSE: A developing agent and a method for manufacturing the same are provided to easily manufacture capsule particles by forming the developing agent and a color erasing agent into respective particles. CONSTITUTION: A particle containing leuco-dye and a developing agent, a particle containing a color erasing agent, and a toner combining agent resin particle, and a medium are contained in a dispersing solution. The particles are coagulated in the medium. The coagulate is thermally welded to form toner particles. The melting temperature of the color erasing agent is higher that the softening temperature of the toner combining agent resin particle. A dispersing solution containing the particle with leuco-dye and the developing agent, a dispersing solution containing the color erasing agent, and a dispersing agent containing the toner combining agent resin particle are respectively manufactured. The particles are atomized in the dispersing solutions.</p> |
