ELECTRIC CHARGE CONTROLLING AGENT, TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE CONTAINING THE SAME, AND METHOD FOR FORMING IMAGE USING THE TONER

摘要

An electric charge controlling agent which comprises agglomerates containing an azo type iron complex salt represented by the following chemical formula [VI]: [VI] wherein B<+> is (H<+>)x(Na<+>)1-x where x = 0.6 to 0.9 or is(H<+>)y(Na<+>)1-y where y = 0 to 0.2, wherein the above agglomerates have an average particle diameter of 0.5 to 5.0 mum; a toner for developing an electrostatic image comprising the charge controlling agent and a resin for a toner; and a method for forming an image of an electrostatic photograph which comprises a step of developing an electrostatic latent image with a developer containing the toner.
