An empirical equation for the light decay curves of zinc-oxide electrophotographic (ZnO) layers is suggested.
In the relatively wide range from the initial value to a value about one third of the initial value, the surface potential of the ZnO-resin layers seems to conform to the equation
V = Vi exp(-α t2)
where Vi: initial value of the surface potential,
α positive constant.
The authors use this equation to quantitatively determine the degree of reciprocity law failure and to determine an intrinsic value for the photosensitivity of ZnO-resin layers.
