PURPOSE:To improve filming characteristic, sensitivity and durability by containing a specific pyrazoline compd. in a photoconductive layer (more particularly the charge transfer layer of laminated type photoconductive layers). CONSTITUTION:The photoconductive layer contg. the pyrazoline compd. expressed by the formula[R1, R2 are H, alkyl, (substd.) aralkyl, (substd.) aryl, said substitutents are OH, halogen, CN, N(CH3)2, etc., R3-R6 are (substd.) alkyl, (substd.) aralkyl, (substd.) aryl, R3 and R4, R5 and R6 may form cyclic amino groups altogether, said substituents are alkyl, 2-hydroxy alkyl, CN, etc., and R7-R10 are H, halogen, alkyl, alkoxy]is formed on a conductive substrate. More particularly, said layer is contained as a charge transfer material in a charge transfer layer. Thus the photoreceptor which is stable against environmental changes and gives superior toner images is obtained. |
