Patent ID: 8039185

Claim:
A toner for developing a latent electrostatic image comprising: a colorant, a wax, and a binder resin, wherein Iwax (s) which is a value measured by FTIR-ATR Spectroscopy before heating a mirror-surfaced pellet formed by compressing and molding the toner, and Iwax (t) which 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), I wax ( t )≧0.2*100/[ T ½(° C.)] Formula (1) I wax ( s )≦0.26 Formula (2) I wax ( t )≦0.50 Formula (3) I wax ( t )> I wax ( s ) Formula (4) wherein Iwax (s) represents a value of before heating the pellet, which is obtained by a formula: absorbance derived from the wax (2850 cm −1 )/absorbance derived from the binder resin (828 cm −1 ), and Iwax (t) represents a value of after heating the pellet at a surface temperature thereof of 130° C. for 1 minute, which is obtained by a formula: absorbance derived from the wax (2850 cm −1 )/absorbance derived from the binder resin (828 cm −1 ).
