  • Toner mass control by surface roughness and voids
    Patent number: 8500616
    Abstract: The present disclosure relates to controlling a performance characteristic of an image forming device component having a surface which may include removal of a portion of the surface to expose a plurality of voids and a surface between the voids. The surface between the voids may have a surface roughness Ra in the range of 0.1 to 5.0 microns and the relationship SAV/(SAV+SAC) is equal to 1-50%, where SAV is the surface area of the voids and SAC is the remaining surface area of the component. The performance characteristic may include the control of toner mass conveyed and/or toner filming and/or the amount of residual toner removed from a photoconductive surface.
