Zusammenfassung:A silica particle contains a nitrogen-containing compound, α/β is 0.30 or greater and 0.80 or less, where α and β are the BET specific surface areas of the silica particle before and after baking at 350° C., respectively, and the absolute ratio of the triboelectric series of the silica particle before baking at 350° C. to that of the silica particle after baking at 350° C. is 0.10 1or greater and 0.85 or less.
