Abstract

See full text

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).
