ABSTRACT:
A charge transporting polymer represented by formula (I-1) or (I-2) and an electrophotographic photoreceptor containing the same: ##STR1## wherein Y and Z each represents a divalent hydrocarbon group; A represents a group represented by formula: ##STR2## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an alkyl group, an alkoxy group, a substituted amino group or a halogen atom; X represents a substituted or unsubstituted divalent aromatic group; n represents an integer of 1 to 5; and k represents 0 or 1; B and B' each represents --O--(Y--O).sub.m --H or --O--(Y--O).sub.m --CO--Z--CO--OR' (wherein R' represents a hydrogen atom, an alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group; Y and Z are as defined above; and m represents an integer of 1 to 5); m represents an integer of 1 to 5; and p represents an integer of 5 to 5000.
The charge transporting polymer has excellent solubility and film-forming properties and can have its ionizing potential controlled.
