Electrophotographic sensitive body

Abstract

PURPOSE: To obtain an electrophotographic sensitive body for a copying machine or a printer having high sensitivity and superior repetitive characteristics by forming a photosensitive layer contg. at least one kind of specified hydrazone compd. CONSTITUTION: A photosensitive layer contg. at least one kind of hydrazone compd. represented by formula I or II is formed. In the formula I, A is an optionally substd. arom. residue, a condensed polycyclic residue or a heterocyclic residue, R 1 is optionally substd. aryl and m is 0 or 1. In the formula II, each of R 2 -R 8 is halogen, alkoxy, optionally substd. alkyl, alkenyl, aralkyl or aryl and n is 0 or 1. A sensitive body having high sensitivity at the time of positive charging and negative charging and superior repetitive characteristics is obtd. COPYRIGHT: (C)1991,JPO&Japio
