Summary:PROBLEM TO BE SOLVED: To obtain a new compound excellent in compatibility with resin binders, also excellent in electron transporting ability and useful for photosensitive layers of electrophotographic photoreceptors in which photosensitive layers are provided on an electroconductive substrate. SOLUTION: This compound is represented by formula I [one or more groups of R1 to R4 are each a group of formula II or the like and the residual R1 to R4, R5 to R8 are each H, a halogen, a (substituted)1-12C alkyl or the like; R9 to R12 are each H, a halogen or a 1-6C alkyl], e.g. a compound of formula III. The compound of formula I is obtained by reacting, e.g. the corresponding phenolic compound of formula IV and V (e.g. 2-tert-butyl-4,6-dimethylphenol) in an organic solvent such as chloroform, in the presence of an oxidizing agent such as potassium permanganate. The compound is used as an electrophotographic photoreceptor to provide the objective electrophotographic photoreceptor excellent in electrical characteristics and repeated stability and having high endurance. The photoreceptor is useful for electrophotographic devices such as printers and copying machines using electrophotographic systems.
