Abstract
An electrophotographic imaging member is disclosed comprising a substrate, a hole blocking, an optional interface adhesive layer, a charge generating layer, and a charge transport layer, the hole blocking layer comprising a light absorbing material selected from the group consisting of a dye, pigment and mixtures thereof dissolved or dispersed in a hole blocking matrix comprising a film forming polymer, the light absorbing material being capable of absorbing incident radiation having a wavelength between about 550 and about 950 nm. The dye or pigment may have a violet, blue, green, cyan or black color. These imaging members may be employed in an electrophotographic imaging process utilizing monochromatic activating radiation having a wavelength between a lower limit of 600 about and an upper limit of about 800 nm to form an electrostatic latent image on the imaging member.
