Flux control of dust particles in a nanometer size range using dc bias voltage is discussed based on dust collection in a divertor simulator employed helicon hydrogen discharges. To discuss mechanisms of flux control, we have estimated etching rate of deposited dust particles due to hydrogen plasma irradiation and have measured current density toward the dc biased substrates. We have found the contribution of the etching can be negligible in a dc bias voltage V_{\text{bias}} range between -50 and 70 V. Clear correlation between V_{\text{bias}} dependence of current density and that of dust flux shows electrostatic force is one of important forces for controlling flux of dust particles.
