Abstract:
A toner comprising a toner particle and inorganic fine particles present on the surface of the toner particle, wherein particle diameter numerical distribution of the inorganic fine particles on the toner particle surface has a peak A1 and B1 present in specific particle diameter ranges, the proportion of inorganic fine particles having a particle diameter of 5 nm to 30 nm is not more than 10 number %, after the toner has been subjected to a water wash treatment, the particle diameter numerical distribution of the of the primary particles of the inorganic fine particles on the toner particle surface has a peak A2 and B2 in specific particle diameter ranges; and HB1, which is a peak value of the peak B1, and HB2, which is a peak value of the peak B2, satisfy a specific relationship.

Claim (Index 1):
A toner comprising:\n a toner particle containing a binder resin and a colorant; and inorganic fine particles present on the surface of the toner particle, wherein particle diameter numerical distribution of primary particles of the inorganic fine particles on the toner particle surface has a peak A1 present in a particle diameter range of at least 35 nm and not more than 55 nm, and a peak B1 present in a particle diameter range of at least 80 nm and not more than 135 nm; in this numerical distribution, the proportion of inorganic fine particles in a particle diameter range of at least 5 nm and not more than 30 nm, with reference to a total number of inorganic fine particles in a particle diameter range of at least 5 nm and not more than 200 nm, is not more than 10 number %; after the toner has been subjected to a water wash treatment, the particle diameter numerical distribution of the primary particles of the inorganic fine particles on the toner particle surface has a peak A2 present in the particle diameter range of at least 35 nm and not more than 55 nm and a peak B2 present in the particle diameter range of at least 80 nm and not more than 135 nm; when HB1 (number %) is a peak value of the peak B1 and HB2 (number %) is ae peak value of the peak B2, 70\u2264(HB2/HB1)\u00d7100\u226490 is satisfied; and the water wash treatment is a treatment in which a dispersion obtained by addition of the toner to surfactant-containing deionized water is shaken for 5 minutes under a condition of a shaking speed of 46.7 cm/second and a shaking amplitude of 4.0 cm.
