To provide a toner for developing a latent electrostatic image comprising at least a colorant, a wax, and a binder resin, wherein Iwax (s) is a value measured by FTIR-ATR Spectroscopy before heating a mirror-surfaced pellet formed by compressing and molding the toner, and Iwax (t) is a value measured by FTIR-ATR Spectroscopy after heating the pellet at a surface temperature thereof of 130° C. for 1 minute satisfy Formulae (1), (2), (3), and (4), <?in-line-formulae description="In-line Formulae" end="lead"?>Iwax (t)>=0.2*100/[T½(° C.)] Formula (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Iwax (s)<=0.26 Formula (2)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Iwax (t)<=0.50 Formula (3)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Iwax (t)>Iwax (s) Formula (4)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein both Iwax(s) and Iwax(t) are obtained by a formula: absorbance derived from the wax (2850 cm<SUP>-1</SUP>)/absorbance derived from the binder resin (828 cm<SUP>-1</SUP>).
