摘要：
A toner is comprised of toner particles containing at least a binder resin and a colorant, and an external additive fine powder. The toner particles have a specific circularity distribution and a specific particle size distribution. The external additive fine powder has an inorganic fine powder having as primary particles a specific number-average particle length, and a non-spherical inorganic fine powder formed by coalescence of particles and having a specific shape factor and a specific number-average particle length.
