ABSTRACT:
A triboelectrically chargeable composition for use in development of electrostatic latent images. The composition comprises a positively chargeable compound and a base material carrying the positively chargeable compound. The positively chargeable compound has an oxidation potential of 750 mV or below, a whiteness W of 0.5 or above and an average particle size of 5.0 microns or smaller. The composition is embodied typically as a positively chargeable toner and also as a charge-imparting material for charging a toner. The positively chargeable toner is especially adapted for development of digital latent images, e.g., as produced by laser beam scanning.
