<p>PURPOSE: To easily provide a toner having satisfactory low-temp. fixability and anti-offsetting property in a heat roller fixing system and not causing block ing at ordinary temp. CONSTITUTION: A core material 1 contg. at least a colorant is suspended in water contg. a dispersant by high-speed stirring and it is encapsulated with fine resin particles 2 to obtain the objective capsulated toner. At this time, satd. fatty acid or satd. alcohol having 40-100 deg.C m.p. is used as the core material 1, and after the resin particles 2 are adsorbed, the surface of the core material is fused by heating and the resin particles 2 are fixed.</p> |
