摘要
One kind of dual layer function separated architecture photoreceptors was prepared. As compared with that of single layered photoreceptor made of the same photogenerator material, their absorption spectra and electrophotographic properties were investigated systematically. The experimental results indicate that phthalocyanine compounds are appropriate photogenerators. The existence of CTL in the dual layered photoreceptor efficiently accelerated photodecay process and bring about a lower V-r value, and higher light sensitivity than that of single layered photoreceptor. These are attributed to carrier injection from CGL to CTL. The process might be interpreted as assistance sensitization effect based on carrier injection. It might play an important role in promoting the performance of dual layered photoreceptor.
