Abstract: A single-layered photoreceptor was made by incorporating charge generation material(CGM),electron transport material (ETM) and hole transport material (HTM) into polymer matrix .At the present stage ,several kinds of phthalocyanine were used in CGM,TNF in ETM and three kinds of donor type molecules(DEH,ECH and TNF)were used in HTM. Photoreceptor containing Y-TiOPc as its CGM was found to show excellent bipolar xerographic performances and extremely high sensitivities in wavelength range of 750~850 nm. The half decay exposure at 820 nm was 0.28 μJ/cm2 for positive charging and 0.22 μJ/cm2 for negative charging respectively.

Key words: organic photoconducctor, single-layered photoreceptor, three components
