Patent ID: 6884559

Claim:
An electrophotographic imaging method in which a liquid developer directly contacts an electrophotographic organic photoreceptor to develop an image, wherein a binder contained in a surface layer of the organic photoreceptor comprises a polyester resin having a main chain of a biphenylfluorene repeating unit represented by Formula 1: wherein hydrogen atoms on aromatic rings are unsubstituted or substituted with one selected from the group consisting of a halogen atom, an aliphatic hydrocarbon group having 1 to 20 carbon atoms and a cycloalkyl group having 5 to 8 carbon atoms, wherein the content of the polyester resin having the biphenylfluorene repeating unit represented by Formula 1 in the main chain is 50 to 100% by weight based on the total weight of the binder.
