Abstract
Photoconductive layers containing a crystallization inhibiting mixture of at least two different organic photoconductors selected from the class of photoconductors represented by the following formula ##STR1## wherein R is selected from the group consisting of alkyl, aralkyl, and substituted and unsubstituted aryl; PA0 X and X' which may be the same or different are selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxyl, NO.sub.2 and halogen; PA0 Y and Y' which may be the same or different are selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxyl, halogen and NO.sub.2 ; PA0 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 group having four to ten carbon atoms and cycloalkenyl group having four to eight carbon atoms; or PA0 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, are disclosed.
