METHOD OF DEVELOPING ELECTROSTATIC CHARGE IMAGE

摘要

PURPOSE:To maintain an antioxidation effect and to improve the durability of an org. photosensitive body as well as to prevent the generation of fogging by degraded photosensitivity by developing an electrostatic charge image formed on the surface of the org. photosensitive body with a developer contg. toner particles and carrier particles coated with a resin contg. antioxidant particles. CONSTITUTION:The developer contains the toner particles and the carrier particles coated with the resin contg. the antioxidant and the average grain size of the carrier particles are preferably 20-120mum. The content of the antioxidant is 1-30pts.wt. per 100pts.wt. carrier particles. A hindered phenol among phenolic compd. is more particularly preferable as the antioxidant but the antioxidant is not limited thereto. The resin-coated carrier resin constituting the developer is preferably a silicone resin or fluorine resin. The carrier particles naps on a developer carrier and forms a magnetic brush, by which the developer carrier is rubbed during the developing stage. The antioxidation effect is maintained in this way and the generation of fogging is prevented even if copying is executed many times.
