PURPOSE:To form the titled body having excellent properties of a sensitivity, a repeatability and a durability by providing a sensitive layer contg. a specific hydrazone compd. CONSTITUTION:The titled body contains a hydrazone compd. shown by formula 1 as a charge transfer substance. The representative example of the hydrazone compd. is the compd. shown by formula 2. By incorporating said hydrazone compd. to the titled body, the electron sensitive body having a high sensitivity, a less residual voltage, the high charge transfer efficiency and the sensitive body having a high copy speed are obtd. If the titled body is used as the sensitive body of a repeated transfer type electrophotography in which the repeating stages of a electrostatic charging exposure, a developing and a transfer are repeatedly performed, the titled body having a less fatique degradation by the repeating use and capable of stably maintaining properties under various severe conditions upto a high temp. from a low temp. and a high humidity from a low humidity is obtd. |
