Method for manufacturing core-shell structure fine particles and toner

摘要

The method for manufacturing core-shell structure fine particles, includes adding metal salt into an aqueous medium containing shell particles A and core particles B to thereby attach the shell particles A to the surface of each of the core particles B and the toner contains the core-shell structure fine particles.
(1) The zeta potential of the core particles B and the zeta potential of the shell particles A are the same polarity.(2) |Zeta potential of the core particles B when adding metal salt|<|Zeta potential of the shell particles A when adding metal salt|(3) (Median diameter based on the volume of the core particles B)>(Median diameter based on the volume of the shell particles A).

1. A method for manufacturing core-shell structure fine particles, comprising:
adding metal salt into an aqueous medium in which at least shell particles A and core particles B are dispersed to thereby attach the shell particles A to the surface of each of the core particles B, the shell particles A and the core particles B satisfying the following relationships (1) to (3); (1) A zeta potential of the core particles B and a zeta potential of the shell particles A are the same polarity. (2) |Zeta potential of the core particles B when adding the metal salt|<|Zeta potential of the shell particles A when adding the metal salt| (3) (Median diameter based on a volume of the core particles B)>(Median diameter based on a volume of the shell particles A).
