The invention features an organic photoreceptor that includes: (a) a change transport compound having formula (1) where R?1 and R2¿, independently, are hydrogen, an alkyl group (e.g., a C¿1?-6 alkyl group), or an aryl group (e.g., a phenyl or naphthyl group); R?3¿ is hydrogen or a hydrazone group having formula (i); R?4 and R5¿, independently, are hydrogen, an alkyl group (e.g., a C¿1?-C6 alkyl group), or an aryl group (e.g., a phenyl or naphthyl group); R?6¿ is an aryl group (e.g., a phenyl or naphthyl group); straight or branched alkyl group having at least 7 carbon atoms; a group having the formula -(CH¿2?)n-Ar where n is at least 3, Ar represents an aryl group (e.g., a phenyl or naphthyl group), and one or more methylene groups is optionally substituted with a hetero atom; or a carbazole group having formula (ii) where R?7, R8, R9, and R10¿, independently, are hydrogen, an alkyl group (e.g., a C¿1?-C6 alkyl group), or an aryl group (e.g., a phenyl or naphthyl group); n is at least 3; and one or more methylene groups is optionally substituted with a heteroatom; (b) a charge generating compound; and (c) an electroconductive substrate.
