Abstract:	The controlled transfer of charged, densely distributed polymer particles across narrow air gaps is one of the basic mechanisms in modern printing technology. To understand the detachment and transport of charged particles by an electric field many-body simulation is employed. All relevant forces like Coulomb particle-particle, particle-field or adhesion forces are included. The results of the simulation are validated by experiments where charged polymer particles are transferred from one roller to a neighbouring one. Since polymer particles of the same polarity can form thick layers, short-ranging attractive forces (cohesion) were introduced in the simulation to prevent the particles from being scattered due to their surplus charge. Our computer simulations clearly show that an inter-particle charge transfer mechanism has to be included in the simulation model to get results that conform to the experiment.
