    • This invention relates to a novel organophotoreceptor comprising:

      (a) at least one charge transport material comprising a fluorenone hydrazone having a combination of groups thereon, the combination of groups being selected from the group consisting of a) at least two fluorenone alkylsulfonylphenylhydrazone groups, b) at least two fluorenone pyrrolylhydrazone groups, c) at least two fluorenone benzotriazolylhydrazone groups, d) at least two fluorenone sulfolanylhydrazone groups, e) at least two fluorenone pyrazolylhydrazone groups, f) at least two fluorenone naphthylhydrazone groups, g) at least two fluorenone tetrazolylhydrazone groups, h) at least two fluorenone stilbenylhydrazone groups, and i) at least two fluorenone (9H-fluoren-9-ylidene)benzylhydrazone groups. Some of these fluorenones may be represented by the formula
         where n is an integer between 2 and 6, inclusive; R 1 is hydrogen, an alkyl group, or an aryl group (e.g., phenyl, naphthyl, stilbenyl, benzyl, or tolanyl group); R 2 is an alkylsulfonylphenyl or one of its derivatives; X is a linking group having the formula -(CH 2 ) m -, branched or linear. The compounds may form electrostatic imaging systems in combination with
      (b) a charge generating compound; and
      (c) an electrically conductive substrate.
