Abstract

Disclosed is an overcoated photoreceptor which contains as the charge injecting layer materials comprised of organic selenium or organic tellurium compounds. In one embodiment, the overcoated photoreceptor is comprised of a substrate overcoated with a hole injecting material comprised of organic selenium or organic tellurium compounds, the hole injecting material in turn being overcoated with a transport layer, which in turn is overcoated with a photogenerating layer and finally, an overcoating or top layer of an organic material.

Disclosed is an overcoated photoreceptor which contains as the charge injecting layer materials comprised of organic selenium or organic tellurium compounds. In one embodiment, the overcoated photoreceptor is comprised of a substrate overcoated with a hole injecting material comprised of organic selenium or organic tellurium compounds, the hole injecting material in turn being overcoated with a transport layer, which in turn is overcoated with a photogenerating layer and finally, an overcoating or top layer of an organic material.

Examples of organic selenium and organic tellurium compounds include those of the following formula:

HC xP YY

- Se - Se - HC

wherein X and Y may be the same or different and may be H, CH3 or C2H5.

The organic tellurium compound is a divalent or tetravalent tellurium compound, the divalent tellurium compound being represented by the formula:

R - Te - Te - R

wherein R may be carboxymethyl, 4-acetamidophenyl, 3-hydroxy-4-methoxy- phenyl, 4-hydroxy-3-nitropheny1, 4-hydroxy-3, 5-dinitropheny l and

    9 @L- CH2
wherein Y may be H, alkyl having from 1 to 5 carbon atoms, methoxy, ethoxy, nitro, cyano or acetyl; and the tetravalent organic tellurium compound is represented by the formula:

0

   It (R - C - CH2) - Te -Xm
