The improved image forming method reduces the chance of toner particles of adhering or filming on the surfaces of impression members, thereby enabling the formation of high-resolution image in a consistent and reliable manner. The method uses a charging member 4 for contact charging a latent image carrier 1, a developing member 11 for impression development of a pattern of latent electrostatic image, a transfer member 18 for impression transfer of the developed toner 10, and an impression cleaning member 23 for cleaning the latent image carrier 1 after toner transfer. The toner to be used satisfies one of the following conditions: that it should have an external additive added in an amount of 0.4 to 1.2 wt %; that it should have a volume resistivity of at least 1017 OMEGA cm; that it should incorporate a release agent in an amount no more than 5 wt %; or that it should not include large amounts of fine particles with a size of 5 mu m and less, or coarse particles with a size of 12.7 mu m and more.
