Patent ID: 7820349

Claim:
A toner for electrostatic latent image development comprising: a first component and a second component which are isolated from each other and capable of forming a color when the first component and the second component are brought into reaction with each other, and a photo-curable composition, wherein the toner is substantially colorless when the photo-curable composition is not cured, and is irreversibly controlled to develop a color by irradiating light having a wavelength at which the photo-curable composition is cured, and then heating after the irradiation, the photo-curable composition contains microcapsules which are dispersed therein, the first component is contained in the microcapsules and the second component is contained in the photo-curable composition, and the microcapsules comprise outer shells formed from a thermoplastic resin having a glass transition temperature of from 90 to 200° C.
