In a toner at least containing a binder resin and a colorant, a value obtained by dividing a particle size D50p by a particle size D84p is 1.43 or more and 1.64 or less, wherein D50p and D84p respectively represent particle sizes at 50% and 84% of cumulative number counted from a large-size side in a cumulative number distribution. Further, in the toner, an average degree of circularity of toner particles having a volume average particle size of 1 μm or more and 4 μm or less is 0.940 or more and 0.960 or less. Further, in the toner, a content of toner particles having an average degree of circularity of 0.850 or less is 10% by number or less among the toner particles having a volume average particle size of 1 μm or more and 4 μm or less.
