Abstract
A photoreceptor drum is disclosed with a charge transport layer comprising a substituted terphenyl diamine having the structure of Formula (I): wherein R1 and R2 are independently selected from the group consisting of hydrogen, alkyl having from 1 to 10 carbon atoms, halogen, and phenyl; and wherein at least one of R1 and R2 is not hydrogen.
Claims10
A photoreceptor drum comprising:
- a substrate;
- a charge generating layer disposed on the substrate;
- and
- a charge transport layer disposed on the charge generating layer, wherein the charge transport layer comprises a polymer binder resin, and a charge transport molecule wherein the charge transport molecule is N,N′-bis(4-tert-butylphenyl)-N,N′-bis[4-(n-butyl)phenyl]-[p-terphenyl]-4,4″-diamine, and further wherein the charge transport molecule is present in the charge transport layer in an amount of from about 25 weight percent to about 35 weight percent and the polymer binder resin is present in the charge transport layer in an amount of from about 65 weight percent to about 75 weight percent of the polymer binder resin.

A method of imaging, comprising:
- generating an electrostatic latent image on a photoreceptor drum;
- developing the latent image;
- and
- transferring the developed electrostatic image to a suitable substrate;
- wherein the photoreceptor drum has a charge transport layer comprising a polymer binder resin, a first charge transport molecule and a second charge transport molecule, the first charge transport molecule being selected from the group consisting of N,N′-bis(4-methylphenyl)-N,N′-bis[4-(n-butyl)phenyl]-[p-terphenyl]-4,4″-diamine and N,N′-bis(4-tert-butylphenyl)-N,N′-bis[4-(n-butyl)phenyl]-[p-terphenyl]-4,4″-diamine, the second charge transport molecule being selected from the group consisting of N,N′-diphenyl-N,N′-bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′-diamine, N,N,N′,N′-tetra[4-methylphenyl]-[1,1′-biphenyl]-4,4′-diamine, and N,N-Bis[4-(4,4-diphenyl-1,3-butadienyl)phenyl]-phenylamine, and further wherein the charge transport molecules are present in the charge transport layer in an amount of from about 25 weight percent to about 35 weight percent and the polymer binder resin is present in the charge transport layer in an amount of from about 65 weight percent to about 75 weight percent of the polymer binder resin.
