Effect of different rounding surface treatment process on particle characteristic of RST toner

Abstract

The effect on the particle characteristic of pulverized rounding surface treated toner (RST Toner) by various mixing and rounding processes had been researched in this study. Two surface additives with different BET value and surface treatments are used as the spacer between toner particles during rounding surface treatment process. Based on different post-blending conditions of rounding surface treatment, the relationships between circularity, mixing condition, static charge property, BET and flowabilty are presented. In this study, surface fusion system is used to prepare the RST toner.
