A feasibility study has been performed to simulate the transport of magnetic carriers in a two-component magnetic brush development subsystem of electrophotography. A fundamental model has been established for the magnetic force, which acts on magnetic particles in the magnetic field applied by a magnetic roller. Numerical calculations have been conducted using a simplified model that neglects the interactive magnetic force between carrier particles. The qualitative adequacy of the model has been confirmed by comparing the calculated distribution of the magnetic force with the experimentally observed adherence mode of carrier beads on the magnetic roller. The present method can be utilized to support the design of magnetic brush development subsystems.
