Title: Electrostatic image development magnetic toner
Inventor: UCHIDA MASAFUMI
IPC: G03G9/08
Filed: 1990-11-20
Abstract: PURPOSE:To prevent the fogging and the occurrence of black spots due to the filming on a photosensitive body by specifying the ratio of the silicon atom concentration on the magnetic toner particle surfaces and an X-ray intensity of the silicon in the total magnetic toner particles in a specific range. CONSTITUTION:A alpha/beta value of the ratio of the silicon atom concentration alphaon the magnetic toner particle surfaces being incorporated silicon containing fine particles in the vicinity of the surfaces of the colored resin particles with dry mixing and the X-ray intensity of the silicon of the total magnetic toner particles is 3.0-8.0. The alpha/beta value indicates how deep the inorganic fine particles incorporating silicon are present from the toner surface. Namely since the surface presence of silicon is specified in a specific range, the inorganic fine particles are present at a proper depth from the toner surface and the releasing of inorganic fine particles from the toner is hardly caused and the filming is prevented. In order to control the alpha/beta value, e.g. a soft material is present on the surfaces of the colored resin particles and the occupancy ratio is controlled.
