This invention relates to a novel organophotoreceptor that includes: (a) a charge transport material comprising a fluorenone hydrazone having 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, or i) at least two fluorenone (9H-fluoren-9-ylidene)benzylhydrazone groups. Some of these fluoreneones may be represented by the formula where n is an integer between 2 and 6, inclusive; R1 is hydrogen, an alkyl group, or an aryl group; R2 is an alkylsulfonylphenyl or one of its derivatives; X is a linking group. The compounds may form electrostatic imaging systems in combination with (b) a charge generating compound; and (c) an electrically conductive substrate.
