Abstract

A photoconductive member having a support, amorphous charge generation and charge transport layers and a barrier layer between the support and the charge generation layer. The charge generation layer contains from 0.1 to 10 atomic percent of a conduction controlling impurity. Intermediate and surface barrier layers are also employed and additional transport layers are utilized.
