A toner composition including toner particles including at least a binder resin; and a colorant, wherein the toner composition satisfies at least one of the following relationships (1) and (2):n nB≦14 when 155<A≦180; andn n B ≦0.6 A −79 when 145≦ A ≦155, (1)n nwherein A represents a shape factor SF-1 of the toner composition and B represents a content of toner particles having a particle diameter not greater than 3 μm; andn nB≦14 when 0.920≦ A ′≦0.950; andn n B ≦394−400 A ′ when 0.950<A′≦0.965 (2)n nwherein A′ represents an average circularity of the toner composition and B represents a content of toner particles having a particle diameter not greater than 3 μm. |
