Along with technological innovations for improving the efficiency of printing, nanoparticles have been added to the surface of toners, and there is concern about the harmful effects of those components. We investigated, through a long‐term observation following intratracheal instillation using rats, whether exposure to a toner with external additives can cause tumorigenesis.
