Abstract

Provided is a toner containing a binder resin. The binder resin contains a crystalline resin. The toner has a maximum endothermic peak temperature (P1) of from 50° C. to 80° C. and a total endothermic amount (Q) of from 35 J/g to 90 J/g at a first temperature elevation of differential scanning calorimetry. A ratio (Qp/Q) of a total endothermic amount (Qp) of the toner in a temperature range of from 20° C. to the maximum endothermic peak temperature (P1) to the total endothermic amount (Q) of the toner is from 0.65 to 0.83.
