New phenylazomethylene-cyclohexadienone derivatives comprising electron withdrawing group and electrophotographic photoconductor comprising the same

摘要

The electrophotographic photosensitive member is disclosed comprising cyclohexanone derivative and this diethoxy-methylene novel phenylazo. Phenylazo methylene according to the invention-diethoxy-cyclohexadiene derivative is represented by the following formula, ; In the formula, R ₁ and R ₂ are independently a carbon group of 1 to 20 substituted or unsubstituted alkyl group, having 1 to 20 carbon atoms substituted or non-substituted or unsubstituted aryl of unsubstituted alkoxy group, having 6 to 30 carbon atoms in each , substituted or unsubstituted aralkyl group, and a halogen selected from the group consisting of any one of 7 to 30 carbon atoms; A is a nitro group, a cyano group, a group composed of any one selected from sulfone group; Wherein l is an integer from 0 to 4; m is an integer wherein 0 to 4; And wherein n is a natural number between 1 to 5; the electrophotographic photosensitive member according to the present invention, and is characterized in that the said phenyl-azo-methylene-characterized in that the containing diethoxy-cyclohexadiene derivative. According to the invention there is an effect that can provide an electrophotographic photosensitive member capable of improving the electrical properties and providing excellent image quality. ; Electron-withdrawing, phenylazo methylene-diethoxy-cyclohexadiene derivative, the photosensitive member
