Abstract
A positively chargeable toner for electrostatic latent image development includes toner particles. The toner particles each include a toner core containing boron nitride and a shell layer disposed over a surface of the toner core. The boron nitride is contained in an amount of no less than 0.05% by mass and no greater than 35% by mass relative to total mass of the toner core. The boron nitride has a thermal conductivity of no less than 40 W/m·K and no greater than 220 W/m·K.
