Abstract:
1. An electrophotographic image forming method comprising steps of: electrically charging a photoreceptor, imagewise exposing the photoreceptor so that a latent image is formed on the photoreceptor, supplying a lubricant on a surface of the photoreceptor, developing the latent image with a toner so that a toner image is formed on the photoreceptor, transferring the toner image, and removing residual toner on a surface of the photoreceptor by a cleaning device; wherein the photoreceptor has an electro-conductive substrate, a photosensitive layer and a protective layer containing inorganic particles, a ratio RSm/D a skewness of a surface roughness profile of the photoreceptor in the direction making a right angle with the driving direction of the photoreceptor Rsk is from −3.0 to 0.0.
