Electrophotographic and hole transport properties of organic photoconductor layers on the base of a phenyltolyl-(β-naphtylamine) (PTNA) doped polycarbonate (PC) and pure (binderless) PTNA were investigated. PTNA was doped into different PCs of types PC-A and PC-Z. Hole drift mobility measured by conventional time-of-flight techniques in the PTNA+PC films was lower than that in the binderless PTNA films. Electrophotographic properties of OPC drums on the base of the PTNA and DEH doped PC layers were studied. An influence of light-, corona- and light + corona intensities on the electrophotographic characteristics of the OPC drums with stabilized or non stabilized charge transporting and generating layers was investigated as well. A stabilization of the electrophotographic layer compounds by various additives such as an antioxidant, an ultraviolet absorber, and an agent for preventing light- and corona induced deterioration was performed.

  • 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.
