<p>PROBLEM TO BE SOLVED: To provide a toner excellent in durable stability while achieving both of storage property and low-temperature fixability.SOLUTION: The toner comprises toner particles obtained by mixing toner base particles comprising a binder resin, wax, and a colorant with boron nitride particles, and then subjecting the toner base particles to a surface treatment with hot air. The binder resin comprises a polyester resin and has an acid value of 5 mgKOH/g or more. The boron nitride particles have a number average particle diameter of 0.02μm or more and 1.00μm or less of primary particles and have a total content of Ca, Mg and Al of 50 ppm or more and 10000 ppm or less based on the mass of the boron nitride particles.</p> |
