Abstract
An image forming device including a photoreceptor with a protective layer, a contact charger; and a metal cleaning blade, wherein the cleaning blade includes a first region and a second region facing the photoreceptor, the first region is of a predefined roughness, and J>h×(cos α/sin β)×d, where α is an angle between the first region and a tangent plane of the second region, β is an angle between the first region and a tangent line of the surface of the photoreceptor at a point of contact with the cleaning blade, h is an amount of depletion of the cleaning blade in a direction perpendicular to the surface of the photoreceptor at the point of contact when the surface of the photoreceptor travels a unit of distance, and d is a predicted total travel distance of the surface of the photoreceptor in a defined time period.
