Agent stirring method and device in magnetic brush cleaning device

Abstract

Abstract PURPOSE:To improve cleaning performance by mixing a material which is larger than carriers for cleaning, has smaller specific gravity, and electrostatically charges toner to the same polarity with carriers as a stirring agent with carriers for cleaning. CONSTITUTION:The stirring agent M is mixed with carriers C used for the magnetic brush cleaning of an electrophotographic copying machine. The stirring agent M may use the material which has larger size and smaller specific gravity than carriers C and electrostatically charges toner to the same polarity with the carriers, e.g. iron of the same kind with the carriers, iron powder coated with fluororesin, ferrite powder of hollow structure and a glass material is usable. Consequently, stirring effect is improved without spoiling the flowability of the carriers C, the electrostatic charge amount of toner T sticking on the carrier C is improved to improve the cleaning performance.
