Claim 19:
20. A method of manufacturing a colored resin particle dispersion containing colored resin particles and water,
the colored resin particles containing a water-insoluble chain polymer and at least one dye selected from the group consisting of an oil-soluble dye, a disperse dye and a vat dye,
the water-insoluble chain polymer having a structure represented by the following General Formula (G), a cyclic structure, and a hydrophilic group, and
the method comprising:
a step (1); and
a step (2),

wherein the step (1) is a step of obtaining an emulsion by emulsifying a mixture containing water, an organic solvent, a water-insoluble chain polymer having a structure represented by the General Formula (G), a cyclic structure and a hydrophilic group, and at least one dye selected from the group consisting of an oil-soluble dye, a disperse dye and a vat dye,
the step (2) is a step of removing the organic solvent from the emulsion obtained in the step (1), and
a mass ratio of a content of the water-insoluble chain polymer to a content of the dye in the mixture of the step (1) is 0.1 to 2.5,, in the General Formula (G), Rg represents a hydrogen atom or a substituent, Lg represents —O—, —S—, or —NRz-, Rz represents a hydrogen atom or a substituent, and * represents a bonding position.
