A photoconductive element having improved physical properties is disclosed. The photoconductive element comprises an electro-conductive substrate, a photoconductive layer containing a photoconductive material and, optionally, a protective layer, wherein either one of said photoconductive layer or said protective layer contains a compound which has in its molecular a hindered amine structure unit represented by formula [Ia] and a hindered phenol structure unit represented by formula [Ib]; <IMAGE> [Ia] <IMAGE> [Ib] wherein, R1, R2, R3 and R4 independently represent a hydrogen atom, an alkyl group, or an aryl group; Z represents a group of atoms necessary to complete a nitrogen-containing alicyclic group; R5 represents an alkyl group; R6 is a branched alkyl group; R7, R8 and R9 independently represent a hydrogen atom, a hydroxy group, an alkyl group, or an aryl group; and R10 represents a hydrogen atom, an alkyl group, or an alkeny group; provided that said hindered amine structure unit is connected through one of R1, R2, R3, R4, R5 and Z thereof, optionally through a divalent organic group and/or one of R6, R7, R8, R9 and R10, with said hindered phenol structure unit, and that R8 and R9 may be connected with each other to form a ring.
