Toner and image forming method using the same
A toner formed of a toner composition containing a resin and a plasticizer, wherein the following relationships (1) and (2) are satisfied:Tg2r>Tg2t  (1),andTg1t−Tg2t>Tg1r−Tg2r  (2),wherein Tg1r represents the peak of the resin for the first temperature rise and Tg2r represents the peak of the resin for the second temperature rise when a differential scanning calorimeter (DSC) measurement is performed for the resin, Tg1t represents the peak of the toner comprising the resin for the first temperature rise and Tg2t represents the peak of the toner comprising the resin for the second temperature rise when a differential scanning calorimeter (DSC) measurement is performed for the toner.
