    • The present invention relates to a photosensitive member with a photosensitive layer on or over an electrically conductive substrate, in which the photosensitive layer comprises at least one of azo pigments selected from the group consisting of azo pigments represented by the following general formulas [I], [II] and [III]. ##STR1## in which Z.sub.1 is a residual group of a condensed ring excluding the benzene ring and the carbonyl group in the formula [I]; Z.sub.2 is a residual group of a condensed ring excluding the naphthalene ring and the carbonyl group in the formula [II]; Z.sub.1 and Z.sub.2 may have a substituent respectively; R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent independently a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, a hydroxy group or a nitro group; Ar.sub.1, Ar.sub.2, Ar.sub.3, Ar.sub.4 and Ar.sub.5 represent independently an arylene group which may have a substituent; Ar.sub.6 represents an aryl group which may have a substituent or a residual group of a coupler component having a phenolic hydroxy group; Cp.sub.1, Cp.sub.2 and Cp.sub.3 represent independently a residual group of a coupler component having a phenolic hydroxy group; n.sub.1 and n.sub.2 represent independently an integer of 0 or 1.
    • 本发明涉及在导电性基材上或上方具有感光层的感光体,其中感光层包含选自由以下通式[I]表示的偶氮颜料组成的组中的至少一种, [II]和[III]。 其中Z1是式[I]中除苯环和羰基之外的稠环的残基; [I] [II] [III] Z2是式[II]中除萘环和羰基之外的稠环的残基; Z1和Z2可以分别具有取代基; R1,R2,R3和R4独立地表示氢原子,烷基,烷氧基,卤素原子,羟基或硝基; Ar1,Ar2,Ar3,Ar4和Ar5独立地表示可以具有取代基的亚芳基; Ar 6表示可具有取代基的芳基或具有酚羟基的成色剂组分的残基; Cp1,Cp2和Cp3独立地表示具有酚羟基的成色剂组分的残基; n1和n2独立地表示0或1的整数。
