Abstract:
A toner according to an embodiment includes a colorant, a binder resin, and an ester wax. The colorant, the binder resin and the ester wax form a toner particle. The ester wax contains two or more ester compounds represented by the general formula R 1 COOR 2 , where R 1  and R 2  each independently is an alkyl group. The total number of carbon atoms of R 1  and R 2  is in a range from 31 to 53. The two or more ester compounds have different number of carbon atoms from each other.

Claim (Index 31):
A method of manufacturing a toner comprising:\n mixing a colorant, a binder resin that contains a crystalline polyester resin, and an ester wax to form a mixture; kneading the mixture; pulverizing the kneaded mixture to form particles; mixing the particles with an aqueous medium to form a liquid mixture; applying mechanical shearing to the liquid mixture to form a fine-particle dispersion; and aggregating fine particles in the fine-particle dispersion to form toner particles, wherein:\n the ester wax contains a plurality of ester compounds, each ester compound represented by the general formula R 1 COOR 2 , where:\n R 1  and R 2  each independently is an alkyl group in which a total number of carbon atoms of R 1  and R 2  is in a range from 35 to 53, and \n each ester compound is grouped in one of a plurality of ester compound groups based on the corresponding total number of carbon atoms, each ester compound group identifiable by the corresponding total number of carbon atoms of each ester compound that is grouped therein, the corresponding total number of carbon atoms being different for each of the plurality of ester compound groups, \n \n a first ester compound group, out of the plurality of ester compound groups, has a maximum content, by weight percentage of the ester wax, among the plurality of ester compound groups having a total number of carbon atoms ranging from 40 to 44, \n a second ester compound, out of the plurality of ester compound groups, has a total number of carbon atoms greater than 44, and \n the ester wax satisfies the formulas 1.03\u2264b/a\u22641.61 and 0.06\u2264c/a\u22640.90, where:\n \u201ca\u201d indicates the content of the first ester compound group by weight percentage of the ester wax, \n \u201cb\u201d indicates the total content by weight percentage of the ester wax of all ester compound groups among the plurality of ester compound groups which have the number of carbon atoms ranging from 40 to 44, including the first ester compound group, and \n \u201cc\u201d indicates the total content of all ester compound groups among the plurality of ester compound groups which have the number of carbon atoms greater than 44, including at least the second ester compound group.
