Toner having good durability, good image quality (halftone white haze) and good image density uniformity even when double-sided printing is repeated continuously. In a toner having toner particles containing a binder resin and a colorant and organic-inorganic composite fine particles, the organic-inorganic composite fine particles have a plurality of convex portions derived from inorganic fine particles on the surface of the resin particles, The degree of aggregation is 70% or less, the angle of repose is 30 ° or more, and in the powder fluidity measuring device, a vertical load of 1.63 kPa is applied in the measurement container to the surface of the powder layer of the toner. The total energy TE2 at the second measurement and the total energy at the fifth measurement in the measurement of total energy when the propeller blade is inserted while rotating at a peripheral speed of 10 mm / sec at the outermost edge of the propeller blade A toner having a TE5 ratio (TE5 / TE2) of 0.50 or more and 0.60 or less.
