发明名称 ELECTROSTATIC LATENT IMAGE DEVELOPING TONER
摘要 PROBLEM TO BE SOLVED: To provide an electrostatic latent image developing toner containing toner particles having excellent stress resistance obtained by aggregating particles in a water system, or the like, and also to provide a method for manufacturing the same. SOLUTION: The electrostatic latent image developing toner is obtained by depositing particles for shells on core particles prepared by aggregating particles for cores, wherein the blending ratio of the particles for cores to the particles for shells is 50:50 to 90:10, the particles for shells contain a softer resin b1 and a harder resin b2 than the particles for cores. When the weight average molecular weights of the particles for cores, the particles for shells, the resin b1 and the resin b2 are represented by MwA, MwB, Mwb1 and Mwb2, respectively, the relations MwA<MwB and Mwb1<MwA<Mwb2 hold.
