Abstract: PROBLEM TO BE SOLVED: To obtain a liq. developer capable of controlled or regulated electrostatic charge of particles by having a phosphoric ester, an organic aluminum composite soluble in nonpolar liquid, its hydrate and its mixture in a charge director. SOLUTION: The liq. developer contains a nonpolar liq., a resin, an arbitrary colorant, a charge director and, optionally, a charge controlling agent. The charge director contains a mixture of phosphoric esters of formulae I-III and an org. aluminum composite of formula IV soluble in the nonpolar liq., its hydrate or its mixture. In the formula IV, R1 is H or alkyl and (n) is about 1-6. The amt. of the phosphoric ester of the formula I is about 85-95 mol.% and the amt. of the phosphoric esters of the formulae II, III is preferably about
