摘要:
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), Iwax (t)≧0.2*100/[T½(° C.)] Formula (1) Iwax (s)≦0.26 Formula (2) Iwax (t)≦0.50 Formula (3) Iwax (t)>Iwax (s) Formula (4) wherein both Iwax(s) and Iwax(t) are obtained by a formula: absorbance derived from the wax (2850 cm−1)/absorbance derived from the binder resin (828 cm−1).
