Abstract
A silica composite particle includes a silica particle and a compound in which a metal atom selected from the group consisting of Ti, Al, Zr, V, and Mg bonds to an organic group through oxygen, the silica particle being surface-treated with the compound. A coverage of a surface of the silica composite particle with the metal atom is 0.01 at % or more and 30 at % or less. When a binding energy peak of O1s in an oxide of the metal atom is assumed to be MO1s, a binding energy peak of O1s in SiOis assumed to be SO1s, and a binding energy peak of O1s in the silica composite particle is assumed to be MSO1s, the binding energy peaks being detected by X-ray photoelectron spectroscopy, the formula 0.000452×X−0.059117×X+SO1s<MSOs≤(SO1s−MO1s)/100×X+SO1s is satisfied.
