摘要

The influence of charge control agent (CCA) on tribocharging characteristics of toner particles was examined by thermally stimulated current (TSC) measurements. Thermally stimulated charge decay (TSCD) measurements, similar technique to TSC were also carried out on the same specimens for the TSC measurements. Four kinds of toner, differing in chemical composition and an acrylic spherical powder were used in this study. It was confirmed that the CCA increased the charge to mass ratio of the toner. The peak height of TSC spectrum was larger in the toner with CCA than in those without CCA. However, the CCA did not introduced new traps in toners. These results suggest that the CCA captures charge carriers and/or promotes charge exchange between toner and carrier, but does not store charge carriers in itself. The TSC spectrum did not depend on the chemical composition of toners for corona charging. This result supports the idea, in which the CCA does not store charge carriers in itself. It was confirmed that TSCD measurements give similar results concerning charge traps in toners as TSC measurements.
