Dependence of Toner Tribocharge on Toner Concentration

Abstract

This study experimentally and theoretically investigates the dependence of charge-to-mass ratio (q/m) of two-component developers on toner concentration. It have been found that there are three types in dependence of q/m on toner concentration. Tribocharging toner concentration dependency is governed by the relative difference of charging site numbers between toners and carrier. To interpret the results, new physical model is proposed and compared with the experiments and other models.
