ABSTRACT:
A non-magnetic toner for developing an electrostatic image has non-magnetic toner particles produced by polymerizing in an aqueous medium a polymerizable monomer composition containing at least a polymerizable monomer, a carbon black and an azo type iron compound. The carbon black has a DPB oil absorption of from 110 ml/100 g to 200 ml/100 g, a specific surface area of 100 m.sup.2 /g or below as measured by nitrogen adsorption, a volatile component of 2% or less and an average primary particle diameter of from 20 m.mu. to 60 m.mu., and the azo type iron compound is a compound represented by the following Formula (1). ##STR1##
