摘要： An image forming method, includes: forming a latent electrostatic image on a latent electrostatic image carrier; developing the latent electrostatic image with a toner to thereby form a visible image; transferring the visible image to a recording medium; and fixing the image transferred to the recording medium. The latent electrostatic image carrier includes: a support, a photoconductive layer on the support, and a surface protective layer on the support. The surface protective layer includes a reactant made by cross-linking the following: an electric charge transporting material which comprises a reactive functional group, a cross-linking resin, and a fluorine surfactant. The toner comprises an inorganic fine particle which defines an effective inorganic fine particle amount in a range of 0.8% by mass to 3.0% by mass calculated from the following equation (1): Effective ⁢ ⁢ inorganic ⁢ ⁢ particle ⁢ ⁢ amount ⁢ ⁢ ( % ) = Inorganic ⁢ ⁢ particle ⁢ ⁢ amount ⁢ ⁢ ( % ) SF - 2 ⁢ / ⁢ 100 Equation ⁢ ⁢ ( 1 ) where SF-2 denotes a shape factor of the toner.
