Abstract
A welded seam of an imaging belt comprises a surface roughness. To reduce the surface roughness, the welded seam is treated by compressing a portion of the belt comprising the welded seam and adjacent belt portions and, while compressing, heating the welded seam to a heating temperature near but less than the glass transition temperature of the imaging layer of the belt, then cooling the welded seam to a cooling temperature. The compressing continues while the heating and cooling steps are repeated until the surface roughness is determined to be satisfactory. The process then ceases.
