Photoconductivit of Oxotitanium Phthalacyanine and Nickel Phthalacyanine Composite

摘要

The xerographic properties of negatively charged dual layer photorecetpro (P/R), where Oxotitanium phthaloyacnine (TiOPc) and Nickel phthaloyanine (NiPc) compoite as the charge genration meterial (CGM), and 4-dimethylaminobenzadldyhyde-diphenylhydrazone (DMPH) as the charge transportation material (CTM), have been studied. In these composites, polymorphic transformation occurs and an increased photoconductivity is observed compared with the pure phthalcoyanines, with maximum values at 75
