Organic Photoconductive Materials Used for Electrophotographic Organic Photoreceptors.

Electrophotography is one of the most prevalent copier and printer technologies. Photoreceptors play a major role in the electrophotographic process. Nowadays, organic photoconductive materials have been most widely used for photoreceptors. Azo and Phthalocyanine pigments are major charge carrier generation materials (CGMs). Hydrazones and arylamines are used as charge carrier transport materials (CTMs). Some models for carrier generation and transport mechanisms have been proposed, Based on these models, molecular structural effects of CGMs and CTMs have been investigated and some new compounds showing good performances have been synthesized.
