摘要：
The present invention provides a novel tryptanthrine derivative represented by a general formula: ##STR1## wherein R.sup.1 is an oxygen atom, or group represented by a formula: ##STR2## wherein R.sup.2A and R.sup.2B are the same or different and indicate a hydrogen atom, a cyano group, an acyl group, an alkoxycarbonyl group or an alkyl group, provided that R.sup.2A and R.sup.2B are not hydrogen atoms simultaneously; and R.sup.3A, R.sup.3B, R.sup.3C, R.sup.3D, R.sup.4A, R.sup.4B, R.sup.4C and R.sup.4D are the same or different and indicate a hydrogen atom or an alkyl group which may have a substituent, provided that when R.sup.1 is an oxygen atom, any one of R.sup.3A through R.sup.4D is a cyano group. Such a tryptanthrine derivative has an excellent electron transport capability to be suitably used for the electrophotosensitive material.
