ORGANIC PHOTOSENSITIVE OBJECT FOR ELECTROPHOTOGRAPHY

摘要

PURPOSE: An organic photosensitive object for electrophotography is provided which has a charge transfer material containing 9H-fluorene-9-one hydrazino substituted compounds and derivatives thereof. CONSTITUTION: The organic photosensitive objects comprises the charge transfer material having a core represented by the formula 1(wherein, A is an heterocyclic group, a naphthyl group, a (9H-fluorene-9-ylidene)benzyl group, an alkylsulfonyl group or a stilbenyl group, B is selected from a group consisting of an hydrogen, an alkyl group and an aryl group, with a provision that B is a naphthyl group when A is a naphthyl group); a charge generating compound; and a conductive substrate.
