Electrostatic latent image developing toner, electrostatic latent image developer, image forming apparatus, and apparatus for manufacturing electrostatic latent image developing toner

摘要

A method for forming an electrostatic latent image developing toner including mixing in a stirring tank a resin particle dispersion with at least a colorant particle dispersion prepared by dispersing a colorant and in some cases with a release agent particle dispersion prepared by dispersing a release agent; aggregating in the stirring tank the resin particles with the pigment particles and the release agent particles to form aggregate particles; and then conducting heating in the stirring tank to fuse the aggregate particles, wherein the method further comprises during a fusion step, suppressing with an accumulation suppression unit accumulation of aggregate particles. The accumulation suppression unit is a magnetic field forming unit that forms a magnetic field either continuously or intermittently. The toner has an average sphericity of at least 0.94 but no more than 0.98 and particle characteristics as defined in the specification.
