Abstract

A probe is immersed in the development fluid and reads the photoreceptor potential after image development. This enables the placement of an electrometer external to the development fluid with the probe being immersed in the fluid. The probe is an electrically biased plate having a known surFace reading area, spaced about 0.020 inches from the photoreceptor surface. The potential of the latent image recorded on the photoreceptor will cause the voltage on plate to float to that of the image. The plate is connected to a collector point by an electrical wire. The collector point is a plate mounted on an insulating block. An electrometer, spaced about 0.030 inches from the collector point, then measures the potential at the collector point.
