Abstract

PURPOSE: To perform continuous developing without any degradation in copying image quality by supplying the replenishing developer composed of toner particles and fine silica particles to the start developer composed of carrier, toner particles and fine silica particles thereby replenishing the consumption with the development. CONSTITUTION: In the development of an electrophotographic copier using the developer composed of carrier, toner particles and fine silica particles, the replenishment for the developer having been consurned through repetitive develpment is ac complsihed by supplying of toner particles and fine silica particles. The ratio b(wt%) of the fine silica particles to the toner particles in the replenishing developer is made higher than the above-mentioned ratio a(wt%) in the start developer and the ratios a, b are so set as to satisfy the relations shown by 0.01≤ a<b≤5.
