Abstract
A toner including base particles and external additives on the base particles, the toner satisfying Conditions 1 and 2 defined in the specification, when a number distribution D of particle diameters of powder particles B generated from one base particle A is calculated from a density a of the base particles A and a density b of the powder particles B, where the base particles A and the powder particles B are deposited on an adhesive area and mica respectively by feeding the toner into a vacuumed space from an inlet, and allowing the toner to crush against a surface of a substrate having the adhesive area composed of a carbon tape, and the mica disposed in a manner that the surface is orthogonal to a direction connecting between center of the vacuumed space and center of the inlet, Powder particles B: particles detached from the base particles.
