<p>PROBLEM TO BE SOLVED: To provide an electrostatic latent image developing toner for low temp. fixing which causes no development defects such as fog and filming. SOLUTION: At least binder resin particles, a coloring agent and wax particles having the following property are mixed. The mixture is molten, kneaded, cooled, pulverized and classified. The wax particles have <=3 needle penetration degree and has such a distribution of particle size that proportion of particles having >=50mm mesh is <=2wt.%, the proportion of particles having <=20mm mesh is >=90wt.%, and the proportion of particles having >=5mm mesh is >=50wt.%.</p> |
