    We have studied friction force of magnetic carrier brushes to the photoconductor drum in two-component magnetic developmemt system of electrophotography by a model experiment and the numerical simulation with the Distinct Element Method. Axial and lateral forces of chain-like brushes applied to the photoconductor were measured to clarify the relationship between the lateral friction force and the diameter of carrier particles, magnetic flux density, and the brush length. It was observed that the force was increased in accordance with the increase of the magnetic flux density and decreased with the brush length but the particle diameter did not affect the total force. On the other hand, the numerical calculation deduced that although the total force is not affected by the particle diameter, the individual differential force of the chain was small and the density of contact points of the brush was high for small particles.
