PROBLEM TO BE SOLVED: To provide a production method of a toner for electrostatic charge image development, by which a toner for electrostatic charge image development can be obtained, the toner achieving both of low-temperature fixability and heat-resistant storage property and exhibiting excellent bending resistance of a printed matter obtained by using the toner.SOLUTION: The production method of a toner for electrostatic charge image development includes a step I of obtaining an aggregate X described below in an aqueous medium and a step II of fusing the aggregate X. The aggregate X comprises: resin particles comprising a crystalline polyester (A) having a polyester moiety obtained by using a monomer having a molar average carbon number of 8 to 12; and resin particles comprising an amorphous composite resin (B) including a polyester segment and an addition polymerization resin segment, in which the addition polymerization resin segment contains a structural component derived from an amphoteric reactive monomer by 3 mass% or more and 15 mass% or less. A mass ratio (crystalline polyester (A)/amorphous composite resin (B)) of the crystalline polyester (A) to the amorphous composite resin (B) ranges from 1/99 to 40/60. |
