Each of the toner particles contains, in a surface portion thereof, at least one hydrophobic salt in a state where a cation derived from a first surfactant is ionically bonded to an anion derived from a second surfactant. A ratio of a total mass of the at least one hydrophobic salt to a mass of the toner is 1 ppm or more and 5,000 ppm or less.
