Abstract
PURPOSE: To reduce formation of toner films both on the surface holding latent images and on carrier particle surfaces by the developer to be used for a magnetic brush, by using the carrier prepared by binding magnetic fine particles with fluorine resin to agglomerates of fixed size.
CONSTITUTION: Fine particles of diameter 0.5W50μ, preferably ferromagnetic metals like Fe, Ni, Co, or the like are dispersed in a solution or dispersion of fluorine resin. This slurry is granulated to a desirable particle diameter of 50W500μ, e.g. by spray drying. The ratio of the fluorine resin to the magnetic fine particles is in the range of 35W70 : 100 by wt.. Whether the surfaces of the magnetic fine particles are coated perfectly or partially with the binder, is properly decided in accordance with the desired property of the carrier particles.
