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 SA/(SA+SA) is equal to 1-50%, where SAis the surface area of the voids and SAis 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.

Toner mass control by surface roughness and voids

This invention comprises a fuser belt ( ) of polyimide incorporating surface-oxidized boron nitride. The resulting enhanced flexibility provides continuing strength without physical damage during use of the belt in a belt fuser while thermal conductivity is preserved. The extent of flexibility enhancement observed is dependent on the degree of oxidation. Therefore, oxidation temperature and time of oxidation are key variables that are used to control the degree of oxidation and thereby the resulting improvement in the flex fatigue.
