During the developmental period of photo copiers, toner is used to make a copy of the document on the paper. The toner was simply a carbon powder, for the past two decades. Then, to improve the quality of the photocopy, carbon was melt-mixed with a polymer. Photo copiers use fuser oil (primarily, Di-methyoxy siloxane), which melts the toner particles and then bind on the paper. This gives a glossy effect and the best quality in fusion of toner particles. But it reduces the life span of drum roller, heat roller unit etc. To mitigate these problems and not compromising the glossy effect in the photocopy, nano phased Chromium Oxide may be mixed with the toner. © 2013 IEEE.
