ABSTRACT:
Photoconductive imaging members comprising a supporting substrate, a hole transport layer, and a photogenerating layer comprising disazo compounds selected from the group consisting of: ##STR1## wherein X is selected from the group consisting of: ##STR2## wherein Y is selected from the group consisting of: ##STR3## The photoconductive imaging members possess high cyclic stability, high photosensitivity, good dark development potential, low dark decay values, and excellent panchromaticity. They are non-toxic and may be made inexpensively, which renders them disposable.
