Disclosed is an image forming method, containing a development step of developing an electrostatic latent image formed on an electrostatic image supporting material using a toner formed on a development sleeve in the from of a thin layer to form a toner image, wherein a ten-point average roughness Rz on the surface of the development sleeve is from 3.0 to 5.7 mum, a volume average particle size of toner particles is from 6.0 to 8.0 mum, the content of a volume average particle size of the toner particles of 5.0 mum or less is from 2.2 to 11.0% by volume, a shape coefficient SF-1 of the toner particles that is measured by an image-analyzing apparatus satisfies the relation: 115<=SF-1<=155, and a shape coefficient SF-2 of the toner particles that is measured by an image-analyzing apparatus satisfies the relation: 112<=SF-2<=150.
