Abstract
A toner comprising a toner particle comprising a binder resin, a hydrocarbon wax A, and an ester wax B, wherein assuming that a ratio of a peak intensity attributed to the hydrocarbon wax A to a peak intensity attributed to the binder resin in heating IR measurement in which the toner is held at 100° C. for 10 min is I, where an initial peak intensity ratio upon heating to 100° C. is denoted by I(ini) and a peak intensity ratio upon heating to 100° C. and holding for 10 min is denoted by I(10 min), the I(ini) and the I(10 min) satisfy a following formula (1):(ini)/(10 min)≤0.95 (1).
