Hydrophobic inorganic fine particles, hydrophobic inorganic fine particles production process, and toner |
摘要 |
Hydrophobic inorganic fine particles characterized by being a mixture of at least small-particle-diameter inorganic fine particles having an average primary particle diameter of 5 to 25 nm and having a maximum peak particle diameter of 20 nm or less and large-particle-diameter inorganic fine particles having an average primary particle diameter which is 1.5 to 100 times the average primary particle diameter of the small-particle-diameter inorganic fine particles; the mixture being a mixture having been treated in the same treating tank to subject both the small-particle-diameter inorganic fine particles and large-particle-diameter inorganic fine particles simultaneously to hydrophobic treatment.
