The external additive includes primary particles each standing alone and non-spherical cohesive particles each including cohered primary particles. A proportion of the primary particles each standing alone per 1,000 particles of the external additive is 30% or less, the particles of the external additive in the per 1,000 particles being the primary particles each standing alone and the cohesive particles.
