Abstract
This invention relates to a particle production method of a developer component for developing electrostatic latent images comprising; a step of producing core particles, a step of mixing the core particles with fine particles for surface modification by a mixing means to adhere the fine particles to the surfaces of the core particles; a step of fixing the fine particles on the surfaces of the core particles by a fixing means; and a step of heat-treating the core particles having the fine particles fixed on the surfaces thereof in a hot gas current at 200.degree.-600.degree. C. by a heating means to fix firmly the fine particles on the surfaces of the core particles.
