Abstract

PURPOSE:To form a developing image having high fidelity to originals and stabilized image quality, by mixing and containing 1-30mmu fine particle treated silica and 0.15-5mu inorganic oxide particles in developers in fly development. CONSTITUTION:A developer 10 is prepared by toner particles in 5-25mu diameter obtained after PE wax, magnetic and hydrophobic silica are kneaded at 145 deg.C by a pressurizing kneader and cooled and the classified, and 0.5wt% hydrophobic silica fine particles in 7mmu particle size and 0.5wt% silica obtained after quartz sand is reduced to powder and adjusted in 220-280mmu and further performed with hydrophobic treatment are mixed. Fly developments are performed by using the developer after a layer thickness is controlled by a blade. After 50,000pcs. are developed, a cohesive degree of the developer is within from 8.2% to 9.4- 13.2%. If the cohesive degree is in 0.1%-30, proper developments are performed.
