发明名称 ELECTROSTATIC LATENT IMAGE DEVELOPING CARRIER
摘要 <p>PROBLEM TO BE SOLVED: To provide a developer which prevents color contamination caused by the wear of the carrier during development and with time and which can give an image having excellent color reproducibility, excellent reproducibility of a highlight part and high resolution. SOLUTION: The electrostatic latent image developing carrier is obtained by forming a coating film on the surfaces of magnetic particles. The coating film contains conductive inorganic fine particles and a constant k defined by k[nm<-1> ]=(m<2> +1)/r2×d×(m<2> -1), wherein m=r1/r2, with respect to the refractive index r1 and the particle size d of the inorganic fine particles and to the refractive index r2 of the coating film, is >=0.015 nm<-1> .</p>
