ABSTRACT:
A polymer has stilbenquinone structures as a repetitive unit and an electrophotographic photoreceptor containing the polymer. More particularly, the polymer has an improved electro-transporting capacity in that precipitation does not occur even when the polymer is used as an electron transporter for an electrophotographic photoreceptor in a high concentration.
