PURPOSE:To obtain the titled body having a high response rate and a small residual potential and high sensitivity by incorporating a specific anti- deterioration agent to an electric charge transfer part of a functional separation type electrophotographic sensitive body. CONSTITUTION:A trialkylamine shown by the formula, as an anti-deterioration agent, is incorporated in the electric charge transfer layer 13 of the functional separation type electrophotographic sensitive body which is mounted an electric charge generation layer 12 and the electric charge transfer layer 13 on a conductive substrate body 11. In the formula, R is alkyl group. The anti-deterioration agent is exemplified by triethylamine, tripropylamine, tri-n-butylamine, triisobutylamine and triisoamylamine. The electric charge transfer layer 13 is formed by coating an org. solvent solution of the electric charge transfer material, a binder polymer and trialkylamine on the electric charge generating layer 12 mounted on the conductive substrate body 1, followed by drying it. The used amount of the anti-deterioration agent contd. in said solution is >=0.0001wt%, preferably 0.1-(0.1-2)wt%. |
