Abstract

The states of dispersion of the charge control agents (CCAs) in a toner were investigated by electron probe micro analyzer (EPMA) scanning on the cut surface of the toner flake and were quantitatively discussed with the image processing of the CCA map obtained from the EPMA measurement. The correlation between the CCA particle size and the tribo-electric charging property of the mono-component was found, in which the optimum volume-average CCA size to maximize the tribo-electric charge existed.
It was found by the XPS measurement that the CCA density on the toner surface was higher than that in the toner.
EPMA and XPS are useful for the quantitative analysis of CCA in and on toner.
