In an image forming method, when viewed from the moving direction of a photosensitive body 1, there is disposed, on the upstream side, a first developing roller 61 opposed to and adjacent to the photosensitive body 1 and rotatable in the opposite direction to the photosensitive body 1, while the peripheral speed ratio of the roller 61 to the photosensitive body 1 ranges from 0.8 to 2.0; on the downstream side of the roller 61, there is disposed a second developing roller 62 rotatable in the same direction to the photosensitive body 1, while the peripheral speed ratio of the roller 62 to the photosensitive body 1 ranges from 1.05 to 2.0; and the shape coefficient SF1 of the toners of two-component developing agent ranges from 120 to 170, while the shape coefficient SF2 ranges from 110 to 130.
