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.

A method of making a micro-fluid ejection head structure for a micro-fluid ejection device. The method includes applying a removable mandrel material to a semiconductor substrate wafer containing fluid ejection actuators on a device surface thereof. The mandrel material is shaped to provide fluid chamber and fluid channel locations on the substrate wafer. A micro machinable material is applied to the shaped mandrel and the device surface of the wafer to provide a nozzle plate and flow feature layer on the shaped mandrel and wafer. A plurality of nozzle holes are formed in the nozzle plate and flow feature layer. The shaped mandrel material is then removed from the device surface of the substrate wafer to provide fluid chambers and fluid channels in the nozzle plate and flow feature layer.

A process for dip coating, particularly vertical dip coating, the topcoat layer onto fuser belts used in electrophotographic processes is disclosed. In this process, a C -C alkanol, such as isopropyl alcohol is added to the solvent system for the fluorocarbon topcoat layer. The use of alcohols in this way provides an efficient and effective method and a topcoat layer which is smooth, uniform and has a good finish.
