In the toner, a volume average particle size D50v is 4 mum to 8 mum 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 mum 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 mum or less is 10% to 50% by number or less based on the entire toner particles.
