TONER, IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND CARTRIDGE PROCESS. A toner, including: a binder resin; and calcium carbonate, where the toner has a molecular weight distribution having a main peak in a range of 1,000 to 10,000, and a mid-peak width of the main peak is 8,000 to 30,000, where the molecular weight distribution is obtained by GPC (gel permeation chromatography) of the THF soluble matter of the toner, and wherein the toner contains calcium carbonate in an amount from 5% by mass to 35% by mass. |
