1. A colorless transparent toner comprising:
a binder resin that comprises a crystalline resin having a urethane bond and/or a urea bond; wherein the colorless transparent toner has a ratio {C/(C+A)} of 0.15 or greater, where C represents an integration intensity of a spectrum deriving from a crystalline structure and A represents an integration intensity of a spectrum deriving from a non-crystalline structure in a diffraction spectrum obtained by an X-ray diffraction device; and wherein the colorless transparent toner satisfies the relations:
T1−T2≦30° C. and T2≧30° C., where T1 represents a maximum endothermic peak temperature for a second time temperature rising and T2 represents a maximum exothermic peak temperature for a first time temperature descending as measured by a differential scanning calorimeter in a temperature range of from 0° C. to 100° C. at a temperature rising and descending speed of 10° C./min. |
