The high photosensitivity of azo‐compound‐based photoreceptors is considered to be due to molecular‐aggregation‐induced geminate‐pair dissociation rather than a photo‐induced electron‐transfer reaction. Both agregated and non‐aggregated carrier‐generating materials are employed on order to investigate the mechanism of this process, which has practical implications for the development of electrophotography.
