摘要：
A toner including a binder resin and a colorant which produces a torque of from 1.4 to 2.0 mNm, when a cone rotor having a vertical angle of 60° and grooves on a surface thereof intrudes into a bulk of the toner at an intrusion speed of 5 mm/min for a depth of 20 mm while rotating at a rotation speed of 1 rpm. The bulk of the toner is formed by consolidating 30 g of the toner in a cylindrical container having an internal diameter of 60 mm for 60 seconds with a consolidation load of 585 g.
