Photo-induced and Dark Discharge Mechanisms of High Gamma Photoreceptors
Abstract: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 completely 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. We have found that the good charge acceptance and the high gamma characteristics depend on structural traps. It is mathematically simulated that the x-type metal-free phthalocyanine's own photoresponse to digital image exposure is not deteriorated in spite of charge carrier trappings by structural traps during carrier transport.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
