摘要：
A dry developer composition for an electrostatic latent image is disclosed. The developer composition comprises a magnetic powder-dispersed type carrier comprising a binder resin having dispersed therein a magnetic powder and a toner having adhered thereto inorganic oxide fine particles, wherein at least part of said carrier has previously adhered to the surface thereof inorganic oxide fine particles. The developer composition does not cause background stains over long-term copying even in the relatively initial stage of running.
