Abstract:
1. A toner for developing an electrostatic image, comprising: a first resin; and a colorant, which is prepared by (1) dissolving or dispersing the colorant and the first resin having at least one group reactive with a compound having an active hydrogen in an amount of at least an average of 2 pieces per molecule of the first resin, in an organic solvent to prepare a toner constituent liquid; and (2) mixing the toner constituent liquid with an aqueous medium that includes fine particles of a second resin, and at least one of a crosslinking agent and an elongation agent to perform at least one of a crosslinking reaction and an elongation reaction of the first resin, wherein the toner satisfies the following relationship: wherein, G represents a ratio of a weight of components other than the colorant and the first resin that are included in the toner and are insoluble in the organic solvent, to a total weight of the toner, R represents a weight ratio of insoluble components included in the toner, which are insoluble in the organic solvent, to the total weight of the toner, and R
