Abstract:
The invention provides a transparent toner for electrostatic latent image development, containing a polyester resin and a release agent, the difference between an endothermic peak Tm of the release agent in a temperature increasing process and an exothermic peak Tc of the release agent in a temperature decreasing process when measured by an ASTM method with a differential scanning calorimeter (DSC) is from about 40° C. to about 50° C., and the degree of exposure of the release agent at the surface of the toner as determined quantitatively by X-ray photoelectron spectroscopy (XPS) is about 10% or less.
