PURPOSE:To obtain a high sensitivity and high durability so that the titled photosensitive body can be applied over a wide range of fields where electrophotography is utilized by using a specific compd. as an electric charge transfer material. CONSTITUTION:The compd. expressed by formula I is incorporated into a photosensitive layer. In formula I, R1, R2 denote alkyl groups which may be the same or different as or from each other and may have a substituent, aryl groups which may have a substituent and aralkyl groups which may have a substituent. The substituents are exemplified by halogen atoms of fluorine, base, bromine and iodine, alkyl groups of methyl, ethyl, propyl, butyl, etc. The electrophotographic sensitive body having the high sensitivity and high durability is thereby obtd. |
