Abstract

In the mono-component non-magnetic toner development system, the toner is charged by contacting with the system parts, such as a doctor blade, a development roller and a supply roller. In such systems the toner charging and fluidity is conventionally controlled by the use of extra-particulate additives on the toner surface. However, the influences of the additives on the charging and fluidity of the toner are still not completely understood. In this study we investigated the effect of using sub-micron sized inorganic extra-particulates on the dynamics of the toner charging mechanism by measuring the currents flowing through each of the system parts. Development rollers having various surface properties and toners having different surface concentrations of the toner additives were prepared. By using the current measurement technique, we examined the influences of the additive on the toner charging in the development process. It is shown that the system currents and resulting toner charges are very dependent on the amount of the additives. As a result, we concluded that these additives affect not only the toner mass transport but also the charge transfer.
