The Imaging Society of Japan (ISJ) Technical Committee part III (The technical committee of toner-based material) issues two types of standard carriers for blow-off toner charge measurements. When the standard measurement procedure, the calibrated blow-off apparatus with the standard developer and the standard carriers were employed, the dispersion of the toner q/m values obtained by different operators was very small. The obtained q/m values can thus be used not only for a common measure in commercial transactions, but also for carrying out the selection of materials and quality control in the manufacture of toner and carriers. In this paper, the concepts and applications for aligning the developer materials on the coordinates of tribo-electric series by using the standard carriers are discussed.
