PURPOSE:To increase the sensitivity of a sensitive body by forming layers each contg. a specified compound as the charge generating and transferring layers. CONSTITUTION:A polycyclic quinone pigment represented by formula I is used in a charge generating layer. A ketazine compound represented by formula II is used in a charge transferring layer. In the formula II, each of R1, R2, R5, R6 and R7 is H, halogen, optionally substituted alkyl, alkoxy, optionally substituted aryloxy or substituted amino, at least one between R1 and R2 is substituted amino or alkoxy, each of R3 and R4 is optionally substituted alkyl or optionally substituted aryl, at least one between R3 and R4 is optionally substituted aryl and n=0 or 1. Thus, a laminate type electrophotographic sensitive body having high sensitivity is obtd. |
