PROBLEM TO BE SOLVED: To provide a toner mixture that has suppressed the occurrence of fogging and photoreceptor filming even in a high-temperature and high-humidity environment.SOLUTION: There is provided a toner mixture that contains a toner for electrostatic charge image development and silica aggregate having particle diameters of 12 μm or more and 100 μm or less, and contains the silica aggregate in an amount of 0.01 weight% or more and 0.50 weight% or less relative to the toner for electrostatic charge image development, where when the hydrophobicity of the silica aggregate is A and the hydrophobicity of the silica aggregate after crushing is B, the following formulas (1) and (2) are satisfied. (1) 50≤A≤80 and (2) A-B≤5.SELECTED DRAWING: None
