PURPOSE:To enhance sensitivity, stability, durability, etc., by vapor depositing a compd. selected from specified naphthalene, tetracene, and fulvalene derivs. to form the photocharge generating layer of a laminate type electrophotographic sensitive body. CONSTITUTION:A photocharge generating layer is formed by depositing on a conductive substrate by the vacuum deposition method, a compd. selected from (A) naphthalene derivs. represented by formula I in which X is S, Se, or Te, (B) tetracene derivs. represented by formula II, and (C) fulvalene derivs. represented by formula III in which R<1>, R<2>, R<3>, R<4> are each H or phenyl or 1-5C alkyl, such as tetrathionaphthalene and tetrathiotetracene. Then, an electrostatic charge transfer layer made of a charge transfer material, such as poly-N-vinylcarbazole, is formed on said layer to obtain an intended electrophotographic sensitive body. |
