ABSTRACT:
Development systems and methods for developing using chemically prepared toners are disclosed. The present invention further discloses developers used in development systems. The use of chemically prepared toners with hard magnetic carrier particles with a non-magnetic, cylindrical shell for transporting developers provides excellent benefits with respect to image quality by reducing granularity and by providing a typically constant, stable developer life as shown by the consistent level of charge to mass over time during operation.
