Patent ID: 8546058

Claim:
A method for forming an electrostatic latent image developing toner, the method comprising 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 within the stirring tank containing the aggregate particles, wherein the accumulation suppression unit is a magnetic field forming unit that forms a magnetic field either continuously or intermittently, wherein the developing toner has an average sphericity is at least 0.94 but no more than 0.98, a proportion of particles of which accumulation of a circle-corresponding diameter on a number basis is more than 90% and a sphericity is less than 0.92 is less than 3% by number of particles of the entire toner, a proportion of particles having a sphericity of at least 0.90 but less than 0.95 is at least 20% but no more than 40% of the entire toner, and a proportion of particles having a sphericity of at least 0.95 but no more than 1.00 is at least 60% but no more than 80% of the entire toner.
