| 1. A toner for developing electrostatic latent images comprising:
a binder resin,
a colorant,
a releasing agent, and
a graft polymer produced by graft polymerization of a resin matrix and a macromonomer, the macromonomer comprising at least
one group selected from the group consisting of:
a hydroxyl group,
a hydroxyalkyl group, and
a pyrolidonyl group, wherein:
a complex viscosity η* of the toner at 160° C., obtained by temperature dispersion analysis of the toner in a sinusoidal oscillation
method, is between 3.0×102 and 1.2×103 Pas, and a loss tangent tan δthereof is between 0.6 and 1.8.
