Patent ID: 7785761

Claim:
A transparent toner to be used for a transparent toner image formed with a color toner image on a recording medium, wherein the said transparent toner comprises: a crystalline polyester resin; and an amorphous polyester resin, wherein a thermoplastic resin constituting the transparent toner is made of a resin obtained by melt-mixing the crystalline polyester resin and the amorphous polyester resin under the conditions which require that T (° C.) is predetermined to be from T 0 to (T 0 +30), t (minute) is predetermined to be from t 0 to (10×t 0 ) and the temperature Tα at which the viscosity of the thermoplastic resin is 10 3 Pa·s is from 70° C. to 110° C., wherein T 0 (° C.) is the temperature at which the visual reflectance Y of 20 μm thick film formed by the thermoplastic resin obtained by melt-mixing the crystalline polyester resin and the amorphous resin for a period of time t 0 (minute) is 1.5%, the melt-mixing temperature is T (° C.) and the melt-mixing time is t (minute).
