Toner, method of manufacturing the same, two-component developer, developing device, and image forming apparatus
Abstract:
A toner includes toner particles containing at least binder resin and colorant. The toner particles contain a large-sized toner particle group of particles and a small-sized toner particle group of particles having a volume average particle size smaller than that of the large-sized toner particle group. In the toner, a volume average particle size D50v is 4 μm to 8 μm at 50% in accumulated volume counted from a large particle-side in accumulated volume distribution of entire toner particles; a content of toner particles contained in a toner particle group having a volume average particle size of 7 μm or more is 24% to 47% by volume based on the entire toner particles; and a content of toner particles contained in a toner particle group having a number average particle size of 5 μm or less is 10% to 50% by number or less based on the entire toner particles.
