ORGANIC PHOTOCONDUCTOR COMPRISING CHARGE TRANSPORT COMPOUNDS CONTAINING HETEROAROMATIC HYDRAZONE GROUPS TO PROVIDE EXCELLENT ELECTROSTATIC CHARACTERISTICS

摘要

PURPOSE: An organic photoconductor comprising charge transport compounds containing heteroaromatic hydrazone groups is provided to improve electrostatic characteristics, thereby being advantageously used in the field of an electrophotographic imaging apparatus or its method. CONSTITUTION: The organic photoconductor comprises a conductive substrate and photoconductive component on the substrate, wherein the photoconductive component comprises: (a) a charge transport material represented as formula 1; and (b) a charge-generating compound. In the formula 1, X is a connecting group; Y1 and Y2 are independently phenotiazine, phenoxazine or phenazine group; R1, R2, R3 and R4 are independently alkyl, alkenyl, heterocyclic or aromatic group; and R5 and R6 are independently hydrogen, alkyl, alkenyl, heterocyclic group or aromatic group.
