PURPOSE:To obtain an electrophotographic sensitive body having high sensitivity and maintaining stable electrostatic charge characteristics even after repeated use by incorporating at least one kind of specified trisazo pigment as a photoconductor into a photosensitive layer formed on an electrically conductive substrate. CONSTITUTION:At least one kind of trisazo pigment represented by formula 1 as a photoconductor is incorporated into a photosensitive layer formed on an electrically conductive substrate. In the formula 1, A is a coupler residue having phenolic OH group or a coupler residue of a 2-methylindolenine deriv., e.g., a group represented by formula 2 (where each of R1 and R2 is H atom, alkyl group which may have a substituent or the like and X is a residue forming a polycyclic arom. or heterocyclic ring by condensation with a benzene ring). Thus, a sensitive body having high sensitivity and superior potential stability during repeated use is obtd. |
