Claims25
A photoconductor comprising a supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport component, and a pyrazine, and wherein said charge transport component is comprised of at least one of
- wherein X is selected from the group consisting of at least one of alkyl, alkoxy, aryl, and halogen, said at least one charge transport layer consists of a first charge transport layer and a second charge transport layer, and wherein said pyrazine is present in an amount of 0.01 to 25 weight percent in each of said first charge transport layer and in said second charge transport layer, and wherein said first and said second charge transport layers include an antioxidant of a hindered phenolic present in an amount of from about 1 to about 10 weight percent.
A photoconductor comprising a supporting substrate, a photogenerating layer, and at least one hole transport layer;
- and wherein said photogenerating layer is comprised of a photogenerating pigment, and where said hole transport layer includes a pyrazine of the following structure/formula
- wherein n represents the number of R groups of from 1 to 4,and R is independently at least one of hydrogen, alkyl, alkoxy, aryl, halo, mercapto, thio, amino, acetyl, cyano, furfurylthio, carboxyamide, and pyridyl, and wherein said hole transport layer includes an aryl amine selected from the group consisting of those represented by the following formulas/structures
- wherein X is selected from the group consisting of at least one of alkyl, alkoxy, aryl, and halogen;
- and
- wherein X, Y and Z are independently selected from the group consisting of at least one of alkyl, alkoxy, aryl, and halogen;
- and wherein said pyrazine is present in an amount of 0.01 to 25 weight percent and wherein said at least one hole transport layer includes an antioxidant of a hindered phenolic present in an amount of from about 1 to about 10 weight percent.
