The present invention discloses a color toner providing highly gloss image and
documents with excellent long term storability; an electrostatic latent image developer;
and an image forming method. Disclosed is a color toner comprising a binder resin
and colorant, wherein the weight average molecular weight of the binder resin is
from 6000 to 45000, the toner's glass transition temperature (Tg) is from 40 to
70 C., the loss tangent tan of dynamic viscoelasticity is from 0.1
to 2.5 in the temperature of from the toner's glass transition temperature (Tg)
to the temperature at which the loss modulus (G") is 1105 Pa,
and the toner comprises 3 to 20% by mass of an ester derivative of an alicyclic
compound having 1 or more carboxyl groups, and an electrostatic latent image developer
and an image forming method, which use the color toner.
