Abstract

An imaging member having a substrate, a charge transport layer having charge transport materials dispersed therein, and thereover, an overcoat layer comprising a deletion control agent.

Claims (25)

1. An imaging member comprising:

a substrate; and thereover

a charge transport layer comprising charge transport materials dispersed therein; and thereover

an overcoat comprising a deletion control agent, a crosslinking agent, and a polyamide.

2. An imaging member in accordance with claim 1 , wherein said deletion control agent comprises the following formula I:

wherein R 1 and R 2 and R 3 can be the same or different and represent an alkyl group of from about 1 to about 25 carbons.

3. An imaging member in accordance with claim 2 , wherein R 2 is an alkyl group having from about 1 to about 10 carbons.

4. An imaging member in accordance with claim 3 , wherein R 2 is an alkyl group having from about 1 to about 5 carbons.

5. An imaging member in accordance with claim 4 , wherein R 2 is a propyl group.

6. An imaging member in accordance with claim 2 , wherein R 1 is an alkyl group having from about 1 to about 10 carbons.

7. An imaging member in accordance with claim 2 , wherein R 3 is an alkyl group having from about 1 to about 10 carbons.

8. An imaging member in accordance with claim 2 , wherein R 1 and R 3 are the same and are both an alkyl having from about 1 to about 25 carbons.

9. An imaging member in accordance with claim 8 , wherein R 1 and R 3 are both alkyl groups having from about 1 about 10 carbons.

10. An imaging member in accordance with claim 9 , wherein R 1 and R 3 are both pentyl groups.

11. An imaging member in accordance with claim 10 , wherein R 1 and R 3 are both straight chain pentyl groups.

12. An imaging member in accordance with claim 2 , wherein R 1 and R 3 are different.

13. An imaging member in accordance with claim 12 , wherein one of R 1 , and R 3 is a branched alkyl group having from about 1 to about 25 carbons, and wherein the other of R 1 and R 3 is a straight chain alkyl group having from about 1 to about 25 carbons.

14. An imaging member in accordance with claim 1 , wherein said palyamide comprises N,N′-diphenyl-N,N′-bis(3-hydroxyphenyl)-(1,1′-biphenyl)-4,4′-diamine.

15. An imaging member in accordance with claim 1 , wherein said crosslinking agent is selected from the group consisting of oxalic acid, p-toluene sulfonic acid, phosphoric acid, sulfuric acid, and mixtures thereof.

16. An imaging member in accordance with claim 1 , wherein said overcoat further comprises a deletion control agent selected from the group consisting of (4-N,N-diethylamino-2-methylphenyl)-4-N,N-diethylaminophenyl methane, methylene(3,5-di-tert-butyl-4-hydroxy hydrocinnamate)methane, butylated hydroxytoluene, bis(4-diethylamino-2-methylphenyl)phenylmethane, bis-[2-methyl-4-(N-2-hydroxyethyl-N-ethyl-aminophenyl)]-phenylmethane, and mixtures thereof.

17. An image forming apparatus for forming images on a recording medium comprising:

a) a photoreceptor member having a charge retentive surface to receive an electrostatic latent image thereon, wherein said photoreceptor member comprises a substrate, a charge transport layer comprising charge transport materials therein, and thereover, an overcoat layer comprising a deletion control acent, wherein said charge retentive surface is on said overcoat layer;

b) a development component to apply a developer material to said charge-retentive surface to develop said electrostatic latent image to form a developed image on said charge-retentive surface;

c) a transfer component for transferring said developed image from said charge-retentive surface to another member or a copy substrate; and

d) a fusing member to fuse said developed image to said copy substrate.
