<P>PROBLEM TO BE SOLVED: To provide a toner for electrostatic latent image development, excellent in low-temperature fixability, storage stability and high-temperature offset resistance and capable of forming an image with excellent glossiness. <P>SOLUTION: The toner for electrostatic latent image development comprises at least a binder resin, a colorant, a charge controlling agent and a release agent, wherein the release agent contains a synthetic ester wax and a natural ester wax. When a toner sample is subjected to the measurement with a differential scanning calorimeter by heating from 30°C to 170°C at a rate of 10°C/min, then cooling down to 30°C at a rate of 10°C/min and again heating from 30°C to 170°C at a rate of 10°C/min, the toner sample shows the respective specified temperatures of a start temperature TB of melting, an endothermic peak temperature T1 at a low-temperature side derived from one ester wax, an intermediate endothermic peak temperature T2, and an endothermic peak temperature T3 at a high-temperature side derived from the other ester wax, which are observed during re-heating-up. <P>COPYRIGHT: (C)2013,JPO&INPIT |
