PURPOSE:To obtain an excellent sensitivity characteristic and durability at the time of repetitive use by providing a photoconductive layer contg. a specific hydrazone compd. on a conductive base. CONSTITUTION:The photoconductive layer contg. the hydrazone compd. expressed by the formula I is provided on the conductive base. In the formula I, R1, R2 may be the same and different and respectively denote a hydrogen atom, alkyl group which may be substd., aryl group which may be substd., etc., which may be substd.; R3-R9 denote a hydrogen atom, alkyl group which may be substd., alkoxy group, etc.; R10-R13 denote a hydrogen atom, alkyl group which may be substd., alkoxy group which may be substd., etc. The excellent sensitivity characteristic and repetitive durability are thereby obtd. |
