ABSTRACT:
Disclosed is a dry toner composition which comprises a resin, hydrophilic silica particles having dyes covalently bonded to the particle surfaces through silane coupling agents, and a polymer having at least one segment capable of enhancing the dispersability of the silica particles in the resin and at least one segment capable of adsorbing onto the surface of the silica particles. In one embodiment, the polymer segment capable of adsorbing onto the surface of the silica particles is ionophoric and capable of complexing with a salt, thereby incorporating a toner charge control additive into the polymer.
