PURPOSE:To obtain the titled body having improved sensitivity by incorporating a specific hydrazone compd. to an electrostatic charge transfer layer and a specific pyrazolone dye and a specific indigoid pigment and the prescribed hydrazone compd. to an electrostatic charge generating layer respectively. CONSTITUTION:In the titled body laminated the electrostatic charge transfer layer and the electrostatic charge generating layer on a conductive substrate body in order, the electrostatic charge transfer layer contains the hydrazone comd. shown by formula I, the electrostatic charge generating layer contains one kind of the compd. selected from the pyrazolone dye shown by formula II and the indigoid pigment shown by formula III and the hydrazone compd. shown by formula I. In the fomulas, R1 and R2 are each an aryl or a heterocyclic ring group, R3 and R4 are each an aryl or an alkyl group, etc., R'1-R'4 are each a monovalent group selected from hydrogen atoms, a carboxyl and an alkyl groups, etc., R'5 and R'6 are each halogen atom, etc., R''1-R''4 are each an alkyl and or an alkoxy groups, etc., X1-X4 are each sulfur atom or NH group. Thus, the titled stable body having the remarkably improved sensitivity and a less tendency for generating an influence due to an abrasion of the electrostatic charge generating layer is obtd. |
