Powder Adhesion Measurement Using a Metered Air Pulse

摘要

A blow-off tool has allowed for the measurement of the cumulative distribution of charged toner particle adhesion to a polymer belt. The tool methodology and design are described. The tool is calibrated to obtain the adhesion force using two different techniques, and the measured values agree well with published values using other adhesion measurement techniques. Measurements taken in different environments have yielded significantly different particle adhesions for the same average particle charge.
