Abstract
A non-magnetic toner having a single main ingredient without a carrier has two toner components having different mean grain sizes. The small-size toner component has a lower resistivity than the resistivity of the large-size toner component to achieve a stable mount of electrified charge and thus an excellent image quality during the printing using the toner.
