Photoinduced Discharge Mechanism of High Gamma Photoreceptor and Electrophotographic Performance
An electrophotographic single layer organic photoreceptor consisting of relatively low concentrations of phthalocyanine pigments dispersed in an insulating binder polymer, which is generally referred to as a high gamma photoreceptor, shows the induction effect. Several mechanisms have been proposed to explain this phenomenon. However it is not clear at this time. In this paper, the photo-induced and dark discharge characteristics of the high gamma photoreceptors consisting of x-type metal-free phthalocyanine pigment and polyester polymer are found to be well described by our theoretical model which takes into account the structural trap. The high gamma photoreceptor is characterized by high gamma photoinduced discharge, slow dark decay, good charge acceptance, a little discharge during induction exposure period, low residual potential and sensitivity change due to repetition of charging and exposure. The characteristics described above can be well explained by our theoretical model which takes into account the structural trap.
