Abstract:
1. An image forming method comprising: developing a latent image formed on an organic photoreceptor, with a developer comprising a toner having a variation coefficient of shape coefficient of not more than 16%, wherein the organic photoreceptor comprises a cylindrical substrate and a layer covering the substrate including a photosensitive layer, wherein the cylindrical substrate has a cylindricity of 5 to 40 μm, and the photoreceptor satisfies the relation of wherein PWS is an average value of power spectrum values of regular reflection light amount in a region of a space frequency from 0 to 2 mm −1 measured at the wave length of imagewise exposing light to the photoreceptor, and P is an average value of reflection light at the measuring point of the photoreceptor.
