Significance and Use
5.1 This test method measures a fundamental property of a toner and developer mix used in copiers and printers. This test method is used for quality control purposes and to determine the ability of the toner and developer materials to develop onto the photoreceptor.
5.2 This test method may be used to measure the chargeto-mass ratio of new developer mixes.
5.3 This test method may be used to measure the chargeto-mass ratio of developer material samples taken from a machine.
5.4 This test method may be used to measure the toner concentration of new developer mixes.
5.5 This test method may be used to measure the toner concentration of developer material samples taken from a machine.
1. Scope
1.1 This test method describes a technique for measuring the tribocharge or charge-to-mass ratio of a sample of developer material.
1.2 This test method determines the concentration of toner in a sample of developer material.
