Abstract
A method of manufacturing a developing agent, comprising the steps of forming a aggregate containing resin particles and a colorant, forming a dispersion by dispersing the aggregate, a first polymerizable monomer, and a semi-polymerizable monomer in a solvent, the semi-polymerizable monomer being obtained by partially polymerizing a second polymerizable monomer, forming a composite seed containing the aggregate, the first polymerizable monomer, and the semi-polymerizable monomer by stirring the dispersion to granulate the aggregate and polymerizing the composite seed in the presence of a soap-free polymerization initiator.
