An image forming method comprising:developing a latent image formed on a cylindrical electrophotographic photoreceptor having a cylindricity of 5 to 40 .mu.m, with a developer comprising toner in which a ratio Dv50/Dp50 of a 50% volume particle diameter Dv50 to a 50% number particle diameter Dp50 is 1.0 to 1.15, a ratio Dv75/Dp75 of a cumulative 75% volume particle diameter from the largest volume particle diameter Dv75, to a cumulative 75% number particle diameter from the largest number particle diameter Dp75, is 1.0 to 1.20, and the number of toner particles having a particle diameter of 0.7.times.Dp50 or less is 10 percent by number or less, to form a toner image; andtransferring the toner image from the photoreceptor to an intermediate transferring member, is disclosed.
