About that time of Nobel Prize 2000 in Chemistry for the discovery and development of conductive polymers, a group of organics called as organic semiconductors began to attract a great deal of attention for the electronic materials. Past three decades, organic electronic materials,
namely “Organic Photoconductors, OPCs, achieved a great success as electrophotographic photoreceptors of copying machines and laser beam printers after many years' efforts. The deep understandings on the charge generation and transport as well as charge injection at the interface
of organic layers in organic photoreceptors established the fundamentals of electronic processes in a wide range of organic materials, which are consisted of inherently insulating molecular assembly. Recently, on a flag of “Organic Electronics”, these materials are thrown into
many electronic devices such as organic electroluminescent EL devices, and more recently, organic FET transistors, organic memories, and solid state organic solar cells. Especially, great efforts have been devoted to achieve paper-like displays or electronic papers, exploiting their advantages
for large area, flexible devices. In this talk, the historical progresses of OPCs in past 30 years will be reviewed briefly and let us consider what we are now aiming at with organic electronic materials, which are generally said to be inferior to inorganic silicon semiconductors in their
electrical properties, and find a scenario to an advanced imaging world drawn with organic electronics. If the time permits, our recently developed novel opto-electronic device combining an organic EL diode and organic photo-electrical conversion layer will be introduced.

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.
