PROBLEM TO BE SOLVED: To solve the problem in which: in a toner for electrostatic charge image development using resin coating pigment as colorant, pigment particles being colorant can hardly be contained in toner particles in a stable manner; and therefore, a manufacturing method of toner for reliably introducing colorant pigment in toner particles has been desired.SOLUTION: The present invention has been reached through finding of a toner containing colorant pigment in toner particles in an efficient, stable, and reliable manner and a manufacturing method thereof by selecting and combining a resin composition that is a core of a toner particle and a coating resin composition of colorant. The core is an emulsified polymer of an aromatic polyester or an acrylic ester monomer having an aromatic polyester as a seed, and a coating resin of the colorant pigment is a polymer having an acrylic ester-based monomer as a main component. |
