An object of the invention is to provide: a toner such that the toner corresponds to a low-temperature fixing system, is excellent in both of offset resistance and anti-heat preservability and especially, even after a large number of copies are to be produced over a long period, the toner does not aggregate to each other, deterioration of flowability, transferability, and fixing ability is extremely rare, the toner makes it possible to form stable images on any transferring medium without transfer errors and with good reproducibility, and further does not contaminate fixing unit and images; or the like. Therefore, provided is a toner comprising: na toner material; and nresin fine particles on a surface of the toner; nwherein the toner has a glass-transition temperature, Tg, of from 30°C to 46°C, the resin fine particles have a glass-transition temperature, Tg, of from 50°C to 70°C, and nwherein, when the toner has been masticated with Labo Plastomill, the toner has a 1/2 flown-out temperature of from 95°C to 120°C, and before the mastication of the toner, the toner has a 1/2 flown-out temperature of from 120°C to 145°C. |
