ABSTRACT:
A triboelectrically chargeable composition for use in development of electrostatic latent images. The composition contains triazine type compound represented by the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different groups selected from hydrogen atom and electron-donating groups which are more electron-donative than hydrogen atom, all of R.sub.1, R.sub.2 and R.sub.3 not being hydrogen atom. The composition is embodied typically as a positively chargeable toner and also as a charge-imparting material for charging a toner.
