Patent ID: 7232635

Claim:
A method of forming a toner image, comprising: electrically charging a photoreceptor by a charging roller being brought into contact with the photoreceptor, the photoreceptor comprises a photosensitive coating layer on a cylindrical conductive substrate, and Formula (2) are held, 0> P max>2 P, Formula 1 2≦( P max/ D )×100≦50, Formula 2 wherein P (μm) is the average of the coating layer thickness in central section in the width direction of the photoreceptor, P is in a range of 15-35 μm, Pmax (μm) is average of the maximum value of the layer thickness out of the image forming region, Pmax is in a range of 10 to 60 μm, and D (μm) is average of distance between point, at which said maximum value is obtained, and edge of the coating layer; imagewise exposing the photoreceptor so that a latent image is formed on the photoreceptor; developing the latent image with toner so that a toner image is formed on the photoreceptor; transferring the toner image on an image forming material; and removing a residual toner on the photoreceptor.
