ARYLAMINE-BASED COMPOUND, ELECTROPHOTOGRAPHIC PHOTORECEPTOR BY USING THE SAME AND IMAGE-FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an arylamine-based compound without reducing its electric characteristic, excellent in durability in the repeated use of an electrophotographic photoreceptor on using as an electric charge transfer substance in the photosensitive layer of the electrophotographic photoreceptor, also exhibiting an excellent electric characteristic and its durability on combining with an electric charge-generating substance such as a phthalocyanine-based pigment, etc. SOLUTION: This arylamine-based compound is expressed by general formula (I) [wherein, X1to X4are each independently H or a substituted vinyl group expressed by general formula (II), and at least two of the X1to X4are the substituted vinyl group expressed by the formula (II) (wherein, R1is H, an alkyl or an aryl; and at least one of R2, R3is a condensed polycyclic aryl group or a condensed polycyclic heterocyclic ring group)].
