Organic electron donor compounds for use in electrophotographic constructions tend to suffer from problems of molecular weight non-uniformity and oxidation. Bis-benzocarbazole derivatives have been found to resist the oxidation and oligomerization which are a source of these problems. These organic electron donor compounds have been found to be sensitized by polyquinoid and polyanthroquinoid dyes.
