Abstract
[Problems] To provide a novel compound which has a high carrier mobility and is useful as a charge-transporting agent that is not only capable of stably forming a photosensitive layer without precipitating crystals or forming pinholes at the time of forming the photosensitive layer but is also capable of forming an organic photosensitive material for electrophotography that has a high sensitivity and a low residual potential.
