Title:
ELECTROPHOTOGRAPHIC SENSITIVE BODY
Document Type and Number:
Japanese Patent JPH01230058
Kind Code:
A
Abstract:

PURPOSE: To improve the spectral sensitivity characteristic, copying reproducibility and repetitive characteristic of the above photosensitive body by constituting a charge generating material of at least two layers; a charge generating material contg. a polycyclic quinone compd. and a charge generating material contg. a specific compd.

CONSTITUTION: The charge generating material of the electrophotographic sensitive body constituted by laminating the charge generating material and charge transfer layer on a conductive base is constituted of at least the two layers; the charge generating material contg. the polyclic quinone compd. and the charge generating material contg. the compd. expressed by formula I. In formula, Ar1 and Ar2 respectively denote a substd. or unsubstd. residual arom. carbon ring group or substd. or unsubstd. arom. residual heterocyclic group; R1 and R2 respectively denote a hydrogen atom. or electron- attracting group; at least one of R1, R2 is an electron-attracting group. A is expressed by formula II, where X denotes a hydroxy group, etc.; Y denotes a hydrogen atom., etc.; Z denotes the atom. group necessary for constituting a substd. or unsubstd. heterocyclic arom. ring, etc.; Z denotes the atom. group necessary for constituting a substd. or unsubstd. heterocyclic arom. ring, etc. The excellent performances in the sensitivity, copying reproducibility and repetitive characteristic is thereby obtd.
