Toner for developing electrostatic image, method for manufacturing the toner, developer including the toner, container containing the toner, and color image forming method using the toner

摘要

A toner for developing an electrostatic image having a good combination of hot offset resistance and low temperature fixability. The toner includes (1) a resin having at least one group that can react with a compound having an active hydrogen in an amount of 2 pieces per molecule of the resin, and a colorant. The toner satisfies the following relationship: 3<=G=R-R_ideal<=20, where G represents a ratio of a weight of components other than the colorant and the resin that are insoluble in the organic solvent to total weight of the toner, R represents a weight ratio of components included in the toner that are insoluble in the organic solvent to the total weight of the toner, and R_ideal represents an ideal weight ratio of the colorant and the resin, which is calculated from a formula of the toner.
