A strip of predetermined thickness and sufficient width is attached adjacent to the edges of spreader and wiper blades used in toner cartridge assemblies for printers, copiers and facsimile machines. The strip provides heat dissipation and distortion prevention characteristics to previously manufactured spreader and wiper blades. The strip is made of heat reflective material and might be a ductile metal such as aluminum or plastic which has elastomeric properties. The strip is attached to the blade by adhesive, metal plating, or by other methods. In one embodiment the strip is placed on the blade such that it is relatively flat. In another embodiment the strip is applied to the blade such that the strip forms an upstanding lip protruding angularly from the blade adjacent to the blade's edge. The strip or lip on the blade does not contact the roller on which toner is being spread or from which toner is being wiped. The lip may have spaced openings which provide for increased rates of heat dissipation, and the openings in the lip may have different depths and widths.
