Abstract:
A method of forming a toner image, comprising:electrically charging a photoreceptor comprising an organic photosensitive layer provided on a cylindrical substrate; 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 to a recording material from the photoreceptor; and cleaning residual toner on the photoreceptor by cleaning blade; wherein the photoreceptor is installed so that the center axis of the cylinder is to be almost horizontal, front edge of the cleaning blade is pressed against surface of the photoreceptor so that cylindrical center angle &bgr; of the cylindrical photoreceptor is at an angle of within Â±30Â° with respect to 0Â° of the vertical line passing the center axis of the cylindrical photoreceptor, ratio of width of the photosensitive layer of the photoreceptor to length of the cylindrical electroconductive substrate is 80/100 to 99/100, and a number ratio of toner particles having a shape coefficient of 1.2 to 1.6 is at least 65 percent in the toner particles.
