The relation between electrical, photoelectrical and electrophotographical properties of polyester polymer–CdS composites as a function of component weight ratio, electric field strength and light intensity were investigated. Cl and Cu activated CdS a powder as well as unactivated CdS powder were added to polyester polymer. It has been shown that the composite containing from 60 to 70 wt‐% of CdS a has the best photoelectric properties. The electrophotographical layers of this composite exhibited a photosensitivity as high as 1.25 (Lx · s) −1 . The results have been explained in terms of the reduction in interparticle barrier height assisted by the localized trapping of photoexcited or field‐excited holes.
