<p>PURPOSE:To easily reduce toner particle diameters and to enhance fixability by forming an oily liquid mixture composed essentially of a resin having cross- linkable parts and its cross-linking agent and a colorant and introducing it into an aqueous medium to emulsify the particles and separating them from the aqueous medium to drying the particles. CONSTITUTION:The toner is prepared through the manufacturing processes comprising the first process of mixing the resin having the cross-linkable parts, its cross-linking agent, the colorant, and additives in a solvent, the second process of introducing the mixture into water to emulsify the particles, the third process of treating them with an acid or a base, and the fourth process of separating them from the aqueous medium and drying them to obtain the dry toner powder. In the third process, separation of the toner particles from the aqueous medium is made easy and permitted to proceed smoothly to the following process by treating them with the acid or the base.</p> |
