Claim Text:
1. A toner comprising: a toner particle that contains at least a resin component, the resin component containing; a first resin as a major component, and a second resin, wherein; the first resin is a polyester-type resin, the polyester-type resin has; a terminal end at which an aliphatic compound has been condensed, and the aliphatic compound being selected from the group consisting of: an aliphatic monocarboxylic acid having a peak value of the number of carbon atom in the range from 25 to 102, and an aliphatic monoalcohol having a peak value of the number of carbon atom in the range from 25 to 102, and the content of a long-chain aliphatic hydrocarbon group that originates with the aliphatic compound is from at least 0.1 mass % to not more than 20.0 mass % in the polyester-type resin, and wherein: the second resin is a crystalline polyester resin, and in a total heat flow of the toner obtained by measuring the toner with a temperature-modulated differential scanning calorimeter, the toner has an endothermic peak resulting from the crystalline polyester resin in the temperature range from at least 50.0° C. to not more than 100.0° C., and the percentage of an endothermic quantity of the endothermic peak in a reversing heat flow with respect to an endothermic quantity of the endothermic peak in the total heat flow being at least 20.0%.
