Abstract

A photoconductive element containing a transport substance and an azine, wherein the azine is a transport substance having the molecular formula: ##STR1## wherein R₁ -R₆ can be different or the same constituents, and are hydrogen or C₁ -C₄ alkyl groups. The transport substance is preferably a tri-aryl amine or a substituted stilbene compound. These photoconductive elements reduce the deterioration of the photoelectrical properties.

Claims

1. A photoconductive element containing a transport substance and an azine,

wherein the azine is a transport substance having the molecular formula:

##STR14## wherein R₁ -R₆ can be different or the same constituents and are selected from the group consisting of hydrogen and C₁ -C₄ alkyl groups.

2. A photoconductive element according to claim 1, wherein the transport substance is selected from the group consisting of triaryl amines and substituted stilbenes.

3. A photoconductive element according to claim 2, wherein the substituted stilbene compound is a compound having the molecular formula:

##STR15## where R₇, R₉ and R₁₀ may be different or the same substituents and are selected from the group consisting of hydrogen and C₁ -C₄ alkyl groups and R₈ can be a substituent selected from the group consisting of hydrogen C₁ -C₄ alkyl groups, an aryl group and alkyl substituted aryl groups.

4. A photoconductive element according to claim 3, wherein R₇ and R₉ are hydrogen and R₁₀ is a methyl group.

5. A photoconductive element according to claim 3, wherein R₇, R₉ and R₁₀ are hydrogen and R₈ is a phenyl group.

6. A photoconductive element according to claim 2, wherein the tri-aryl amine is tritolyl amine.

7. A photoconductive element according to claim 2, wherein the tri-aryl amine is a compound having the molecular formula:

##STR16##
