Abstract
A cleaning blade is used to clean a photoreceptor surface in an electrophotographic marking system. The elastomeric blade contains an amount of carbon nanotubes that improves the mechanical, electrical and thermal properties for cleaning the photoreceptor surface. The nanotubes can be disposed throughout the elastomer in the blade or can be dispersed only at a tip of the blade or only in the bottom section of the blade.
