TONER AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a toner preventing fusion to an electrode, capable of uniform saturation electrostatic charge in a short time and capable of stably forming a satisfactory image over a long period of time and to obtain an image forming device using the toner. SOLUTION: A toner 16 with about 0.01-3 pts.wt. fine powder of Al2 O3 or TiO2 as an abrasive material 16e added to 100 pts.wt. bonding resin 16a is used. When the toner almost causes fusion to an aperture electrode, a toner stripping effect is produced. The toner 16 does not fuse even under high stress and uniform electrostatic charge of the toner 16 is attained in a short time.
