Patent number: 5460911Abstract: 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.Type: GrantFiled: March 14, 1994Date of Patent: October 24, 1995Assignee: Xerox CorporationInventors: Robert C. U. Yu, Geoffrey M. T. Foley, William G. Herbert, William W. Limburg, Satchidanand Mishia, Richard L. Post, Neil S. Patterson, Donald C. VonHoene

Patent number: 5139907Abstract: A layered photosensitive imaging member is modified by forming a low-reflection layer on the ground plane. The low-reflection layer serves to reduce an interference fringe contrast and according to a second aspect of the invention, layer adhesion is greatly improved when selecting TiO.sub.2 as the low-reflection material. In a preferred embodiment, low-reflection materials having index of refraction greater than 2.05 were found to be most effective in suppressing the interference fringe contrast.Type: GrantFiled: July 13, 1990Date of Patent: August 18, 1992Assignee: Xerox CorporationInventors: Yonn K. Simpson, Edward F. Grabowski, Donald J. Teney, Satish R. Parikh, Neil S. Patterson
