    摘要: A developer for developing an electrostatic latent image comprising colored electroscopic particles and at least one silicon dioxide powder having its particles made hydrophobic with a specified organosilicon compound is disclosed. Silicon atoms in said organosilicon compound are bonded to silicon atoms on the surface of individual silicon dioxide particles through oxygen atoms. At least one organic group in the organosilicon compound has a total carbon number of 8 or more and is a saturated or unsaturated aliphatic organic group with at least 5 carbon atoms or an organic compound having a hydrocarbon ring. In a preferred embodiment, such a silicon dioxide powder is used in combination with another silicon dioxide powder whose particles are rendered hydrophobic by an organosilicon compound wherein any of the organic groups present has a total carbon number of 7 or less and is a saturated or unsaturated organic group with not more than 4 carbon atoms or an organic group having a hydrocarbon ring.
