Abstract:
A toner having chargeability and fluidity that do not change to a great extent is provided. The toner includes toner particles containing a binder resin and includes inorganic fine particles A, wherein the shape factor SF-2 of primary particles of the inorganic fine particles A is 116 or less, and regarding the particle size distribution on a volume basis of the inorganic fine particles A on the toner particle surfaces, the particle diameter when a cumulative value from the small particle side reaches 16% by volume is denoted as D16, the particle diameter when a cumulative value reaches 50% by volume is denoted as D50, and the particle diameter when a cumulative value reaches 84% by volume is denoted as D84, D50 is 80 nm or more and 200 nm or less, and the particle size distribution indicator A represented by D84/D16 is 1.70 or more and 2.60 or less.
