Abstract:
A process for making a developer roll sleeve, the process comprising the steps of:(a) providing a core substrate roll having an outer circumferential surface; (b) surface finishing said outer circumferential surface sufficient to provide a surface roughness of at least about 1 Ra; (c) coating said outer circumferential surface with a conductive composition comprising a thermosetting resin, a conductivity additive and a wear-resistance imparting additive, wherein said composition is provided in an amount sufficient to obtain a thickness wear rate of less than about 4.7Ã—10âˆ’4 percent per printing cycle based on an initial thickness of said conductive composition of not more than 300 microns, and wherein said conductive composition is coated onto said core substrate roll by a method other than extrusion; and (d) thermosetting said conductive composition coated on said core substrate roll.
