Photoconductor element, regenerating methods and elements useful therein

Claim 1

A photoconductor element of interbonded successive layers comprising: (a) a substrate; (b) an electrically conductive, hole injecting layer; (c) a charge transport layer comprising at least one organic photoconductor dissolved in a binder polymer; and (d) a charge generating layer comprising a dye sensitized photoconductor dissolved in a binder polymer; wherein said organic photoconductor is selected from the class of compounds having the formula: ##STR12## wherein R is selected from the group consisting of alkyl, aralkyl and substituted and unsubstituted aryl; X and X', which may be the same or different, are selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxy, NO 2 and halogen; Y and Y', which may be the same or different, are selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxyl, halogen and NO 2 ; A and B, when taken alone may be the same or different, are selected from the group consisting of hydrogen, alkoxy, hydroxyl, halogen, substituted or unsubstituted aryl, alkyl, cycloalkyl having four to ten carbon atoms, and cycloalkenyl having four to eight carbon atoms; or A and B, when taken together, represents sufficient atoms to form together with the carbon to which they are attached a substituted or unsubstituted carbocyclic ring having from 4 to 10 carbon atoms; wherein each said organic photoconductor may be present in said layer up to the limit of its solubility int he binder; and wherein A and/or B in at least one of said photoconductors is substituted or unsubstituted aryl.
