Abstract
(EN) A toner for electrophotography which contains at least a binder resin, a coloring agent and a mold release agent. If the binder resin (3) is taken as a first resin and the mold release agent is taken as a second resin, a third resin A (4), which has low compatibility with the first resin, is of a different kind from the second resin and has a weight average molecular weight of less than 4,000, is dispersed in the first resin with an average particle diameter of 0.2-0.5 μm.
(FR) La présente invention se rapporte à un toner pour électrophotographie qui contient au moins une résine liante, un agent colorant et un agent de démoulage. Si l'on suppose que la résine liante (3) est une première résine et que l'agent de démoulage est une deuxième résine, une troisième résine A (4), qui présente une faible compatibilité avec la première résine, qui est d'un type différent de celui de la deuxième résine et présente une masse moléculaire moyenne en poids inférieure à 4 000, est dispersée dans la première résine avec un diamètre particulaire moyen compris entre 0,2 et 0,5 μm.
(JA)  少なくとも結着樹脂、着色剤および離型剤を含む電子写真用トナーであり、結着樹脂(3)を第1の樹脂、離型剤を第2の樹脂として、第1の樹脂との相溶性が低くかつ第2の樹脂とは樹脂の種類が異なる重量平均分子量4000未満の第3の樹脂A(4)が、第1の樹脂中に0.2~0.5μmの平均粒径で分散されている。
