| 1. An image forming method, comprising:
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; and
fixing the image transferred to a recording medium,
wherein the latent electrostatic image carrier comprises:
a support,
a photoconductive layer on the support, and
a surface protective layer on the support,
wherein the surface protective layer comprises 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, and
wherein 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):
 wherein SF-2 denotes a shape factor of the toner.
