PROBLEM TO BE SOLVED: To provide an electrostatic charge image development toner excellent in low temperature fixability, heat-resistant storage property, and electrification characteristic, and a manufacturing method of the same.SOLUTION: In an electrostatic charge image development toner and a manufacturing method of the same, a core part comprises a binder resin containing a composite resin (A) and a crystalline polyester (B), and a wax. A shell part comprises a binder resin containing a polyester resin (C). The composite resin (A) comprises: a segment (a1) consisting of a polyester resin which is obtained by performing condensation polymerization of an alcohol component where content of a propylene oxide addition product of a bisphenol A is 80 mol% or more and a polyvalent carboxylic acid component; and a vinyl resin segment (a2) containing a constitutional unit derived from a styrene compound. The crystalline polyester (B) is a crystalline polyester which is obtained by performing condensation polymerization of an alcohol component where content of α,ω-aliphatic diol having 8 or more and 16 or less carbon atoms is 80 mol% or more and a polyvalent carboxylic acid component where content of an aliphatic saturated dicarboxylic acid having 8 or more and 16 or less carbon atoms is 80 mol% or more. The polyester resin (C) is a polyester resin which is obtained by performing condensation polymerization of an alcohol component where content of an ethylene oxide addition product of the bisphenol A is 80 mol% or more and the polyvalent carboxylic acid component.SELECTED DRAWING: None |
