A method for producing a charge controlling agent comprisinig a reaction product
of an aromatic hydroxycarboxylic acid and a calcium compound bonded by at least
one bondinig system selected from the group consisting of coordinate bonding, covalent
bonding and ionic bonding, characterized in that the aromatic hydroxycarboxylic
acid and the calcium compound are reacted by dropwise adding a solution of the
aromatic hydroxycarboxylic acid to a solution of the calcium compound as a metal-imparting
agent, a charge controlling agent produced by said method, which has a shape coefficient
(SF-1) average value of at most 250 and a shape coefficient (SF-2) average value
of at most 200, and an electrostatic image developing toner containing said charge
controlling agent having a presence ratio on a toner surface of at least 2.0 mg/1
g of toner.
