Original Abstract Submitted
A method for manufacturing a surface-treated sol-gel silica particle that can impart good flowability when added into a toner and has little change in charge during environment change; a manufacturing method therefor; and an external additive for a toner containing the surface-treated sol-gel silica particle. The method includes steps of: (A1) obtaining a hydrophilic sol-gel silica particle having a silanol group on a surface and substantially composed of a SiOunit; (A2) adding a compound having a (CH)Si— group or a RRSi— group, and introducing a (CH)SiOunit or a RRSiOunit on a surface of the hydrophilic sol-gel silica particle to obtain a preliminarily treated silica particle; and (A3) adding a compound having a RSi— group, and further introducing a RSiOunit on a surface of the preliminarily treated silica particle to obtain a surface-treated sol-gel silica particle.
