Abstract
Provided is a toner manufactured in an aqueous solvent, whereby a satisfactory image density can be obtained and the toner laid-on level on a recording medium can be reduced with a normal added concentration of pigment without adding a large quantity of pigment to the toner. The toner is manufactured in an aqueous medium by the suspension polymerization or dissolution suspension method and contains a binder resin, a pigment and an azo compound. The azo compound is a specific azo compound, and the absolute value of the difference in zeta potential between the binder resin and the azo compound is 25 mV or less.
