FERRITE PARTICLES AND ELECTROPHOTOGRAPHIC DEVELOPER CARRIER USING SAME, ELECTROPHOTOGRAPHIC DEVELOPER, AND METHOD FOR PRODUCING FERRITE PARTICLES
There are provided ferrite particles in which Mn ferrite is used as the main phase and which contain Sr ferrite, where the degree of projections and recesses in the surface of the particles falls within a range of 2.5 to 4.5 µm, and the standard deviation of the size of grains appearing on the surface of the particles falls within a range of 1.5 to 3.5 µm. In this way, a coating resin is left on the surface of the particles even after long-term use and thus a decrease in the charging property is reduced.
