PROBLEM TO BE SOLVED: To provide toner which has high print density and causes no fog in various environments and which can be surely transferred from a photoreceptor to a transfer material. SOLUTION: The toner contains a binder resin, a colorant and conductive inorganic fine particles having≤1×10<SP>4</SP>Ωcm powder resistivity and has 3 to 10μm volume average particle size and 0.94 to 0.995 average circularity measured by flow type particle image analysis.
