ABSTRACT:
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 δ 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 1×105Pa, 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.
