Amorphous Silicon Photoreceptors: Homogeneity of Electrophotographic Properties
Abstract:Small pixel size or high resolution necessary for gray scale and color reproduction requires a high uniformity of the electrophotographic properties of the photoreceptor. The uniformity of the properties depends mainly on the thickness of thin layers and interfaces in the multilayer photoreceptor structure and doping uniformity. Structure and properties of a-Si:H photoreceptors meet these essential requirements. We investigated the preparation of a-Si:H photoreceptors and the electrophotographic properties: charge acceptance, dark decay, exposure-voltage-(E-V-) characteristic, residual potential and sensitivity. We have shown that an non-uniformity below ± 3 % in respect of the full photoreceptor surface can be achieved.

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.
