<P>PROBLEM TO BE SOLVED: To provide a toner for developing an electrostatic latent image excellent in low-temperature fixability and heat-resistant storage property, and to provide a method for producing the same. <P>SOLUTION: There are provided a production method of a toner for developing an electrostatic latent image includes the following steps (1) to (3), and the toner for developing the electrostatic latent image obtained by the method. The method comprises: (1) mixing resin particles (A) containing a polyester resin (a) of 90 wt.% or more; release agent particles containing wax and a polyester resin (b) having a softening point of 75 to 105°C in the weight ratio (wax/polyester resin (b)) of 95/5 to 55/45; and a flocculant in an aqueous medium to obtain aggregated particles (1); (2) mixing resin particles (B) containing a polyester resin (c) to be a shell into the aggregated particles (1) to obtain aggregated particles (2); and (3) fusing the particles constituting the aggregated particles (2) to obtain core-shell particles. <P>COPYRIGHT: (C)2012,JPO&INPIT |
