resulting dispersion composition is coated as a photosensitive layer on an electrically conductive substrate any of known hole transporting substances and electron transporting substances can be used as the charge transporting substance in the present invention as preferred examples of the hole transporting substance there can be mentioned poly n vinylcarbazole phenanthrene n ethylcarbazole 2 5 diphenyl 1 3 4 oxadiazole 2 5 bis 4 diethylaminophenyl 1 3 4 oxadiazole bis diethylaminophenyl 1 3 6 oxadiazole 4 4 39 bis diethylamino 2 2 39 dimethyltriphenyl methane 2 4 5 triaminophenylimidazole 2 5 bis 4 diethylaminophenyl 1 3 4 triazole 1 phenyl 3 4 diethylaminostyryl 5 4 diethylaminophenyl 2 pyrazoline and p diethylaminobenzaldehydo diphenylhydrazone as preferred examples of the electron transporting substance there can be mentioned 2 nitro 9 fluorenone 2 7 dinitro 9 fluorenone 2 4 7 trinitro 9 fluorenone 2 4 5 7 tetranitro 9 fluorenone 2 nitrobenzothiophene 2 4 8 trinitrothioxanthone dinitroanthene dinitroacridine dinitroanthraquinone and tetracyanoquinodimethane these compounds may be used singly or in the form of a mixture of two or more of them of course there may be adopted a method in which a complex of an electron receptor and an electron donor is used as the charge transporting substance so that both the holes and electrons can be transported in the case where the charge transporting substance is a low molecular weight substance it is necessary that the charge transporting substance should be used in the state dispersed in a binder resin such as mentioned above and in the case where the charge transporting substance is a high molecular weight substance having a binding property in order to increase the mechanical properties and enhance the adhesion it is preferred that a binder.
