Abstract:
JRecently
a new model was proposed to explain the dependence of triboelectric
charging characteristics of two-component developers on toner
concentration. According to the model, there are three types in dependence
of toner charge-to-mass ratio, q/m, on toner concentration. The dependence
of triboelectric charging characteristics on toner concentration is
governed by the relative difference of number of charging sites between
toners and carriers. The influence of coating materials on carrier surface
to toner charge has been studied by the measurement of dependence of toner
q/m on toner concentration. JThe results of experiment agree with the
proposed triboelectric charge model of earlier studies. It is found that
the toner tribocharging characteristics is changed by carrier surface
modification. The results of uncoated ferrite carrier are labeled as Type
I and uncoated iron carrier are behave as Type II. In the case of silicone
coated carrier, the two cases of the
triboelectric charging characteristics are expressed. The one is changed
from Type I to Type II and the other is still remained at Type I. In the
case of fluorine coated carrier, the triboelectric charging
characteristics changed from Type I to Type III. It is suggested that the
required toner charge system which have image stability and reliability,
etc., can be obtained by a choice of the coating materials and treatment
conditions.
