NOVEL ETHYLENE COMPOUND, CHARGE TRANSPORT MATERIAL CONTAINING THE ETHYLENE COMPOUND, PHOTORECEPTOR FOR ELECTROPHOTOGRAPHY CONTAINING THE ETHYLENE COMPOUND, AND PROCESS FOR PRODUCING THE PHOTORECEPTOR

摘要

The present invention was inhibited and the deterioration of the optical light fatigue enemy, hence preventing the rise of the residual potential can be, and is also useful as a long-term use, the photosensitive member for electrophotography stable to, ethylene-based compound that can stably obtain a good image, the charge transport material containing it, and the photosensitive member for electrophotography containing it provides a method for producing The. The present invention relates to an ethylene-based compound represented by formula I, the charge transport material, photosensitive member for electrophotography comprising it and a method for producing it, including: Formula I In the formula, R ₁ , R ₂ and R ₃ are each independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms or represents an alkoxyl group having a carbon number of 1~6, R ₄ is an alkyl group, a phenyl group or a tolyl group having a carbon number of 1~3, Ar represents an aryl group or a heterocyclic ring having a carbon number of 7 to 20. ;
