A complex system for developing electrostatic images, and particularly a toner which contains a metal complex represented by the formula ##STR1## wherein a or b is a benzene ring moiety or cyclohexene ring moiety with or without C.sub.4 -C.sub.9 alkyl substituents, R.sub.1 and R.sub.2 are each hydrogen, C.sub.4 -C.sub.9 alkyl or a substituent which may be in the form of a benzene ring moiety or cyclohexene ring moiety with or without C.sub.4 -C.sub.9 alkyl substituents, provided that both R.sub.1 and R.sub.2 are not hydrogen at the same time, Me is Cr, Co or Fe, and X is a counter ion such as hydrogen or sodium. The metal complex has good compatibility with the resin component of the toner and is substantially colorless, imparting outstanding durability to the toner.
