Recent technology progress in organic photoconductor OPC is remarkable. Various materials have been developed
and now a variety of OPC are available in the market. Some of them are very high sensitive in visible region. High
sensitive OPC in near IR wavelength have been developed for the laser beam printer application. They have also enough
durability. Now we can select a suitable OPC for most of the applications of the electrophotography. Historical review and
recent technological trends are shown in this paper.
