Toner is used in photocopiers to form the latent electrical image on the electrostatically charged drum. The paper picks up the toner particles, when it slides over the drum. Specific factors cause 10% of toner particles (approximately) to be left over the drum. This left out toner is cleaned by the unit to ensure the quality of the proceeding copies. This left out toner is called as waste toner and is collected in cleaner sump. If this waste toner is used in the photocopiers, the quality of the copier is reduced. The waste toner is mixed in proportion with Nano phase Carbon and original toner to get Hybrid Black Toner. The original toner is the toner prescribed for the photocopier by the manufacturer. The hybrid black toner is characterized by the two parameters say waste toner and nano phase carbon in this article. © 2006-2015 Asian Research Publishing Network (ARPN).
