Abstract
The two stages of degradation in electrophotographic cadmium sulphide binder layers-fatigue and ageing are investigated. The dependences of the photoinduced decay of the potential and the contrast potential vs the exposure time during the first cycle and in fatigue show that this process probably occurs in the bulk of the semiconductor particles. The changes of the photoinduced decay of the potential during the second stage of degradation, ageing, may be associated with changes in the barrier structure.
