Abstract
A core-shell particle includes a core, and a shell on a surface of the core. The core includes a crystalline release agent. A value of a sum of a number-average value of Feret diameter of the core-shell particle and a standard deviation of the Feret diameter of the core-shell particle is 20 to 500 nm. The shell comprises an organosilicon polymer. In a differential scanning calorimetric measurement of the core-shell particle, a maximum endothermic peak is present when a temperature is raised from 30° C. to 120° C. at 10.0° C./min, a maximum exothermic peak is present when the temperature is lowered from 120° C. to 30° C. at 10.0° C./min, and Tc (° C.) is at least 5° C. lower than Tm (° C.) where Tm is a peak temperature of the maximum endothermic peak and Tc is a peak temperature of the maximum exothermic peak.
