Abstract

We have evaluated some azo pigment carrier generation materials in a layered organic photoreceptor in terms of electrophotographic sensitivity and color reproduction, and found a dihydro-thiadiazepine derivative azo pigment which shows high sensitivity and excellent color response. Fixing carrier generation material(CGM) at this dihydrothiadiazepine derivative and selecting some conventional carrier transport materials(CTM), we have investigated effects of carrier mobility in a carrier transport layer(CTL), carrier injection efficiency and carrier generation in CGL on the electrophotographic sensitivity. If we assume carrier generation in carrier genaration layer(CGL) is well represented by carrier peak current, the electrophotographic sensitivity has been found to show the closest corelation with the carrier peak current. The carrier peak current also shows close corelation with carrier life time in CGL which is strongly influenced by CTM. We propose a mechanism that explains how CTM affects electrophotographic sensitivity of layered organic photoreceptor.
