(57) [Summary] [Construction] In an electrophotographic toner comprising toner particles, hydrophobic silica fine particles and alumina fine particles, the toner particles are fine particles having an average particle size of 8 μm or less, and the hydrophobic silica fine particles are the average particles of primary particles. An electrophotographic toner comprising: first hydrophobic silica fine particles having a diameter of 15 to 20 nm; and second hydrophobic silica fine particles having an average primary particle diameter of 13 nm or less. [Effect] Even in a bad environment, the fluidity is good, the rising speed of charging is fast, and stable charging property is obtained. |
