ABSTRACT:
A photoreceptor for positive charging is disclosed, said photoreceptor comprising a carrier generating material which is stable against both heat and light, has high carrier generating efficiency and provides good photoconductivity over a wide wavelength range and a specific carrier transport material combined in such a manner that the shape of surface potential curves remains essentially constant over a cyclic operation and contributes to the formation of a visible image of high quality in each cycle by reducing the "memory effect", minimizing the residual potential and extending the cycle life.
