Toner having good cleaning properties and transferability and capable of forming a high-definition image. A toner is obtained by granulation in an aqueous medium, and includes an external additive composed of a polyester resin, a colorant, and inorganic fine particles. (1) The circularity is 0.95 or more, (2 ) The shape factor SF-2 is 120 to 150, (3) the resistance is 5 × 10 7 to 3 × 10 11 Ω · cm, and (4) the volume average particle diameter (Dv) is 3.0 μm or more. 0 μm or less, the ratio (Dv / Dn) of the volume average particle diameter (Dv) to the number average particle diameter (Dn) is 1.00 or more and 1.30 or less, and (5) the equivalent circle diameter is based on the number. The particle content of 2.0 μm or less is 20% or less. [Selection figure] None |
