Title:
LAMINATE TYPE ELECTROPHOTOGRAPHIC SENSITIVE BODY
Document Type and Number:
Japanese Patent JPS61129651
Kind Code:
A
Abstract:

PURPOSE: To reduce variation of sensitivity and to improve durability by laminating on a conductive substrate an electrostatic charge transfer layer for positive hole transfer, and a charge generating layer contg. a photoconductive azo pigment and an org. photoconductive polymer represented by a specified chemical formula.

CONSTITUTION: The electrophotographic sensitive body is prepared by laminating on the conductive substrate 5 the charge transfer layer 4 contg. a material for transferring positive holes, such as pyrene or N-ethyl carbazole, and on this layer the charge generating layer 3, contg. the org. photoconductive polymer 2 and the photoconductive azo pigment 1 represented by formula I in which A is a divalent org. group forming a conjugated double bond between C atoms combined with an azo group or a group of formula II; B is a coupler having a phenolic OH group; and l is 2 or 3.
