ABSTRACT:
The present invention provides a toner for developing electrostatic latent images, including resin particles containing a crystalline polymer and an amorphous polymer, wherein the amorphous polymer and the crystalline polymer satisfy the relationship represented by the following formula (1), and a method for manufacturing the toner of the invention. The present invention also provides a developer for electrostatic latent images including the toner of the invention and a carrier; and an image forming method using the toner of the invention. Further the invention provides a method for manufacturing a dispersion of resin particles.in-line-formulae description="In-line Formulae" end="lead"?δa−δc≧1.05[(cal/ml)1/2(25° C.)] Formula (1)in-line-formulae description="In-line Formulae" end="tail"?In formula (1), δa represents a solubility parameter of the amorphous polymer, and δc represents a solubility parameter of the crystalline polymer.
