Abstract
Embodiments pertain to a novel imaging member, namely, an electrostatic latent image generating member that can generate an electrostatic latent image digitally without using a raster output scanner (ROS), photoreceptor and charger. The imaging member facilitates the charge injection process between an organic conjugated polymer and N,N′-diphenyl-N,N′bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′diamine charge transport layer.
