Zusammenfassung:A toner, including: a binder resin; and calcium carbonate, wherein the toner has a molecular weight distribution having a main peak in a range of 1,000 to 10,000, and a half value width of the main peak is 8,000 to 30,000, where the molecular weight distribution is obtained by GPC (gel permeation chromatography) of THF soluble matter of the toner, and wherein the toner contains the calcium carbonate in an amount of 5% by mass to 35% by mass.
