Carcinogenicity  :In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possible  human 

carcinogen).  This classification is given to chemicals for which there is inadequate human 
evidence, but sufficient animal evidence on which to base an opinion of carcinogenicity.  The 
classification is based upon the development of lung tumors in rats receiving chronic inhalation 
exposures to free carbon black at levels that induce particle overload of the lung.  Studies 
performed in animal models other than rats did not show any association between carbon black 
and lung tumors.  Moreover, a two-year cancer bioassay using a typical toner preparation 
containing carbon black demonstrated no association between toner exposure and tumor 
development in rats. 

Chronic Effect     : In a study in rats of chronic inhalation exposure to a typical toner, a mild to moderate degree of 

lung fibrosis was observed in 92% of the rats in the high concentration (16mg/m
