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 ,
where carbon black is bound in a resin matrix, 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
