Abstract:
An electrophotographic photoconductor comprising an electroconductive support, and a photoconductive layer formed thereon comprising as an effective component an aromatic polycarbonate resin comprising a structural unit of formula (I) and a structural unit of formula (II): ##STR42## wherein Ar.sup.1, Ar.sup.3, Ar.sup.5 and Ar.sup.6 each may be the same or different, and is an arylene group which may have a substituent; Ar.sup.4 is a phenylene group which may have a substituent, Ar.sup.2 and Ar.sup.7 each may be the same or different, and is a phenyl group which may have a substituent; Y is an ethylene group or vinylene group; and X is a bivalent aliphatic group, a bivalent cyclic aliphatic group, a bivalent aromatic group, ##STR43## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each is an alkyl group which may have a substituent, an aryl group which may have a substituent or a halogen atom; a and b each is an integer of 0 to 4; c and d each is an integer of 0 to 3; and p is an integer of 0 or 1, and when p=1, A is a straight-chain alkylene group having 2 to 12 carbon atoms, --O--, --S--, --SO--, --SO.sub.2 --, --CO--, ##STR44## in which Z.sup.1 and Z.sup.2 each is a bivalent aliphatic group which may have a substituent, or an arylene group which may have a substituent; R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10 and R.sup.11 each is a hydrogen atom, a halogen atom, an alkyl group having 1 to 5 carbon atoms which may have a substituent, an alkoxyl group having 1 to 5 carbon atoms which may have a substituent, or an aryl group which may have a substituent, and R.sup.5 and R.sup.6 may form a carbocyclic ring or heterocyclic ring having 5 to 12 carbon atoms, or R.sup.5 may form a carbocyclic ring or heterocyclic ring in combination with R.sup.1 and R.sup.2 ; q is an integer of 0 or 1, and when q=1, R.sup.12 is an alkylene group having 2 to 4 carbon atoms; r is an integer of 0 or 1, and when r=1, R.sup.13 is an alkylene group having 1 to 4 carbon atoms; and e is an integer of 0 to 4, wherein said photoconductive layer is on the surface or said electrophotographic photoconductor has a surface layer containing said aromatic polycarbonate resin.
