Title: Toner for developing electrostatic charge image
Inventor: ITO KENGO
IPC: G03G9/09
Filed: 1986-01-20
Abstract: PURPOSE:To continuously obtain an image having specified high quality by dispersing a coloring agent in both the binder resin phase and wax phase in toner particles. CONSTITUTION:This toner is formed by dispersing the coloring agent in both the wax phase and binder resin phase in the toner particle. The ununiformity of the electrostatic chargeability of every individual toner is eliminated by dispersing the coloring agent into both the binder resin phase and wax phase, by which the electrostatic flocculation of the toner particles to each other is prevented and the fluidity and shelf life are remarkably improved. The coloring agent is uniformly dispersed by the toner particles and the unevenness by the partial uniformity of the electrostatic load (electrostatic charge quantity) on the toner surface is decreased because the electrostatic charge of each individual toner particle is made uniform.
