    摘要: A toner for developing an electronic latent image, including toner particles containing a binder resin and a colorant, and an external additive, is provided. The external additive contains silica formed by a sol-gel method of which the surface is subjected to hydrophobic treatment and which has an average primary particle size of 80 to 300 nm, a water content of 3 to 15% and a volume resistivity of 1×1013 &OHgr;cm or more. The invention further provides an image forming method and an image forming apparatus using the same. The toner for developing an electrostatic latent image is good in transferability over a long period of time and gives a high image quality without causing an image defect.
