摘要： 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.

摘要： A charge transport layer material for a photoreceptor includes at least a polycarbonate polymer, at least one charge transport material, polytetrafluoroethylene particle aggregates having an average size of less than about 1.5 microns, hydrophobic silica and a fluorine-containing polymeric surfactant dispersed in a solvent. The presence of the hydrophobic silica enables the dispersion to have superior stability by preventing settling of the PTFE particles. A resulting charge transport layer produced from the dispersion exhibits excellent wear resistance against contact with an AC bias charging roll, excellent electrical performance, and delivers superior print quality.

摘要： A novel method and apparatus for producing an endless flexible seamed belt using templates is disclosed. A first form of the template is a mask template with a template aperture in the form of a puzzle cut pattern to be used in combination with an excimer laser. The template is placed between the excimer laser source and the belt material to be cut. As the excimer laser traverses the width of the belt, the laser forms a puzzle cut pattern on the belt. A second form of the template is a punch and die having patterned edges in the form of a puzzle cut pattern with extremely small nodes and kerfs. The cutting tolerances of the patterned edges make it necessary to fix the punch with respect to the die so that there is no misalignment of the punch and die between cutting operations. This is accomplished by resiliently fixing the punch to the die, rather than having the punch attached to the force generating assembly as in normal punch and die assemblies. Belt material is positioned between a stock gap between the punch and die and the force generating assembly is activated to provide the cutting force. Once the belt material is cut, the cutting force is removed and the force generating assembly returns to its retracted position. Both types of templates result in very clean cuts without deformation or distortion.
