INDOLE DERIVATIVE

摘要

[Problems] To provide a novel compound having a high carrier mobility and is useful as a charge transporting agent which not only makes it possible to stably form a photosensitive layer without precipitating crystals or without developing pinholes when the photosensitive layer is being formed but also makes it possible to form an organic photosensitive material for electrophotography of a high sensitivity and a low residual potential. [Means for Solution] An indole derivative represented by the following general formula (1),
wherein R 1 and R 2 are alkyl groups, k is an integer of 0 to 3, j is an integer of 0 to 4, a ring Z is a 5- to 6-membered ring and is, specifically, a cyclopentane ring, and X 1 and X 2 are hydrocarbon groups having at least one ethylenically unsaturated bond.
