PROBLEM TO BE SOLVED: To provide hydrophobic orthotitanic acid microparticles excellent in hydrophobicity, dispersibility, and safeness and usable for various applications such as an outer additive of a toner for electrophotographies. SOLUTION: A substrate consisting of orthotitanic acid is treated with an alkoxysilane in an amount of 50-200 mass%, then neutralized with an acid, filtered, cleaned, and dried at 100-170°C.
