Title:
ELECTROPHOTOGRAPHIC SENSITIVE BODY
Document Type and Number:
Japanese Patent JPH0378752
Kind Code:
A
Abstract:

PURPOSE: To enhance potential stability at the time of repeated uses and to prevent rise of residual potential, deterioration of image density, and background staining by incorporating a specified compound in a photosensitive layer containing an electric charge generating material and a charge transfer material and formed on a conductive substrate.

CONSTITUTION: The photosensitive layer formed on the conductive substrate and containing the charge generating material and the charge transfer material further contains the compound represented by formula I and the like. In formula I, each of R1 - R8 H, hydroxy, halogen, optionally substituted alkyl, such a alkenyl, such aryl, such cycloalkyl, such alkoxy, such aryloxy, wubstituted amino, imino, heterocyclic, optionally substituted alkylthio or arylthio, sulfinyl, sulfonyl, acyl, or azo, thus permitting potential stability at the time of repeated uses to be enhanced and rise of residual potential, deterioration of image density, and background staining to be prevented.
