Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a new compound useful for obtaining an eletrophotographic photoreceptor having a high sensitivity and durability. SOLUTION: This bisazo-based compound is represented by formula I [R is H, a (substituted)alkyl, alkenyl, aralkyl, aryl, acyl, etc.; R and R are each a halogen, OH, nitro, a (substituted)alkyl, alkenyl, aralkyl, etc.; (m) and (n) are each 0-4; K and K are each a coupler residue containing OH group having coupling ability]. Furthermore, the compound is preferably obtained by tetrazotizing, e.g. a diamine represented by formula II according to an ordinary method and subjecting the resultant compound to coupling reaction with the corresponding coupler in an organic solvent such as water/or dimethylformamide at |
